Nikon's booth at CP+ includes Z6 and Z7 cameras running firmware with Eye AF. We tried it out, side-by-side with the Sony a7R III, to see how they compare.
Both cameras do a good job of recognizing the subject's eye and sticking with it, even when she covers her face for a period of time. They're similarly fast to find the eye again, afterward. This recognition (and how quickly it re-acquires the eye) is key to the performance of eye-detect AF, as we're already pretty confident about the Z7's ability to focus when requested.
We weren't able to keep the images from the Nikon but will put it to the test as soon as we have the new firmware.
Correct me if I am wrong but it looks like the higher resolution of Nikon's EVF and display are the trade offs to the overall responsiveness of the system. The eye AF of Nikon could be as responsive as that of Sony's if they have the same resolution (both EVF and display) and refresh rates instead since more processor resources are more devoted to AF calculations than keeping up with what is on the screen at such higher resolutions.
@ MILC man Yes, the 50/1.8 S is a dream lens. ...i was on of the first who got one und i tried to tell everyone here (also DPR :D) how good it is and that DP did one of the biggest mistakes ever with their "wort lens of the year" ranking. - But nearly no one believes me ^^ ...until the new DPR- test ;-) @ StevieF Sadly there is a big technical difference between the old and the new focusing system. The way to go is a combination of AI object/scene detection, an accurate depth detection (little extra sensor or small camera lens) and extra AI computing units in our DSLMs ( like a lot of new smartphones has already) . Believe me in 2 years no one will ever talk about the old 3D tracking. The new Sony AF is only the begin of what you really can do with AI!
Things will get even more interesting if we included Minolta A-mount, then we will have 600/4G and a good set of f2 primes (28mm, 35mm, 50mm and 100mm) plus the world only AF 1:1 macro zoom...
The world is quit a bit bigger than the mighty Nikon world...
putting sony glass on a z-mount body that already has inferior af is not a solution to anything... it's just compounding existing Nikon af issues with weak 3rd-party signal translation problems.
the "bigger lens mount" has not been utilized, it's nothing more than marketing hype.
and there you are inferring that 3rd-party adapters work perfectly on Nikon.
you don't even own Nikon milc, lol, you are a dslr owner who has been bagging on adapters for years now… see how you change your tune, just because it's Nikon ;-)
I do actually own a Nikon Milc, I never said the 3rd party work perfectly READ MY WORDS And then you can fit all your Sony lenses onto a Zed mount with this adaptor.
Sony/Sigma and the Sony's "Fan boys" only claim the adapting lens work perfectly for certain brand of adapters + certain brands of lenses. Time did past but things never changed :)
Also, adapting Sony lenses to the Z body is kind of dumb...only to say Sony lenses are better than the Nikon when we all know who is the one behind fabricating the sensors....unlike adapting Canon lenses, which give the Canon folks a taste of the Sony sensors.
btw, I'm a fan boy of all brands... coz I use and own pretty much most major brand and used them in different professional settings.
Orz.....I guess you guys just proofed who are the fan boys XD I just mention who "FABRICATE" the sensors, which is fact. No need to get defensive. Did I say anything bad about the Nikon camera body design, lens design, sensor performance and Nikon IQ? Not that I can think of.
@ cisnucbide.....why are we still circling around this..does it really matter? We can talk about the full history of each camera brand to no end.
What matter now is if Nikon can sell enough camera to sustain the future. Sales figure have nothing to do with how good the product they develop. If the Sales and Marketing team can't translate all those into revenue. Which is just paper weight at the end.
So far the favor is not on Nikon side. And thats a fact as well. The board of Nikon and a lot of the Nikon users should really look into the reality and to figure out what went wrong.
@Mac We are just responding to what you brought up... I don't think Cosmicnode or I are defensive, just pointing out facts to balance out your comment, so that anyone reading this gets the full understanding of how the industry works.
How this industry work is (and properly all electronic products now a day)..really..is put together parts from global supplier, take advantage of others expertise and then put in their own uniqueness on either cosmetically and/or on the software side. The design/tweaking part is very minimum, as a lot of things are protected by patents. Thats why the longest argument between Sony and Nikon is how it's handle, how shxtty is the menu system, the color science ...but only a tiny little bit is on the actual image quality (except Canon which is really lagging behind with their own manufacturing/fabrication)....because at the end of the day a lot of them are brothers/sisters/cousins under the hood.
If Nikon keep thinking its good enough to build good quality products in their own standard and keep misinterpret the market. The downward trend of their sales will never turn around. It's a mindset problem, not the product's problem.
yes sony will be caught or lose his lead if he does not change the mount ... the hitch! they will hardly receive the new goals sigma for sony ... no changes in riding sony for several years, and this is where nikon and canon will catch up.
i got the z7 and the face detection does an excellent job. don't need any eye detection. its a gimmick and nothing more. all those years i even didn't have face detection and still managed to take some nice portraits
@Golan Ziv, congratulations for blowing 5-10k on a very advanced camera system with the most modern technology that you clearly don't need just to take a couple on nice portraits. Don't bother with the new firmware update, actually just return the camera before your wife finds out what you're up to. ;-)
Can Z6/7 track by Eye when the subject is moving is the question. The model in Richard’s test here was sitting down and the only thing moving was her face. Also I did not gather how the feature works, do you have to press and hold the button like in Sony prior to upcoming Firmware 5.0, or it will look for an eye without you having to press any buttons? Finally is the new EYE AF only going to be available when Z7/6 is in wide area mode, or it can be like Sony/Olympus/Fuji irrespective of area mode, it will look for it?
Competition is good. Glad to see Nikon's upcoming firmware update is catching up the game.
Read a lot of the comments below, I think some of the Nikon folks may miss the point of nailing the eye(s) further away can actually means especially when the Nikon have some ultra fast prime coming into their lineup. The DOF remain relatively shallow in certain situation. Moreover in the test video (0:40s), the barista is really not that far away...
Would love to see how the Nikon do in the moving subjects tracking ability.
Anyway, Nikon's current problem is not in the hardware but their marketing. It would be much better if they can remain humble (as they already have a 100 years of camera making history...just saying..:P), not looking down to the others and most importantly not over hyping their products....
@Macadesigner "It would be much better if they can remain humble (as they already have a 100 years of camera making history...just saying..:P), not looking down to the others and most importantly not over hyping their products...."
You do realize that this whole comment section is filled with Sony paid trolls don't you?
@NexLupus You know that it's Nikon who dig the hole themselves right? They are the one, who said their mirrorless camera is superior to the others...they are the one, who play down the smaller mount size of other brands...they are the one who look down and down play all the technology advancement from all other mirrorless camera manufactures...and no other company can maker better camera than Nikon coz they have 100 years of history on their back....Not even Canon the number one in the whole interchangeable camera market said those things together. And Nikon do...Officially Sony still say they are challenger, and looking for room to improvement.... To be fair, I think all those trolls you are talking about are just the reflection of all the Canonikon trolls to Sony users. And to me some of them just a sarcastic joke making fun, if you take it too seriously you lose :) But you know that's part of the fun of the competitions.
@NexLupus There are no excuses, trolls are trolls. Sometimes its good to look at the mirror (how ironic that we are going into a mirrorless era) and look closely into ones self. Maybe you can also stop rationalizing and start using all the other brands and embrace all the pros and cons of different tools and use it effectively :)
Nikon has face section since forever and it wasn't mentioned over the years. With Nikon dslr you have 3d tracking and that worked great for the eyes. But this is a milc and you need it more as there is no 3d tracking. It is another way of doing the same thing, this would be easier or less effort.
Funny, but SONY fanboys are laughing at Nikon giving EYE-AF and IBIS as they are crying for years. But now, it is a stupid move as Nikon guys are liking the feature is available...
Good to see that Nikon adresses this in a FW-update 👍 way to go and promising for future updates to the Z-system The question is, who will buy into Sonys infrastructure (Jack of all trades, master of none)? Or buy into a true camera company? I'm almost ready to start with Nikon Z7 and all the great features offered 🙂
While Eye focus is not important at all for me and I already have that in my Sony A7r II but hardly use it, it's great to see Nikon doing all kind of development and giving user firmware updated to improve their existing product. they still have a lot more work to do though, I know I will continue to use my Nikon DSLR D850 and D500 and will buy a high end Z body when it arrives, A7R II likely be my last Sony but I like my Loxia lenses so I hope Sony will bring out a larger body with a better ergo then I will upgrade too.
i choose the z7 for simple reason. it has better image quality and it aim for the future. for me personally Sony cameras are nice gadgets. i has the Sony a7r3 for 3 weeks, but wasn't satisfied with image quality and confusing and complicated menus. if im already spend that amount of money i want the best of the best. and the Z7 is the best i found
@Golan Ziv, I am no fan of A7R III ( due to control layout) but really you find A7R III image quality below the Z7 that you can actually see the difference?? seriously?? and in my experience, the Z7 's focus system not even at the same league as the A7R III, that's besides the EYE-Focus capabilities.
yes i truly see the difference. if you have a 5k monitor you can see the difference. the z7 is sharper and its jpg's are looking much better (not a little but much better). the Sony seems to over expose the sky. the always look brighter then they are. abut the focus there is no difference between both cameras. the Sony has the eye af and Nikon face detection. didn't even had problem with 1 picture. i also shoot at night. perfect camera. sorry but the sony is over hyped camera. i mean its very good camera that i believe will be more the enough for most people. but those who search the ultimate IQ will find it on the z7 or fuji gfx 50r, buy the way i have the fuji xt3 which is better then the sony (except in low light) its IQ and colours are superior to Sony in every aspect. if the sony was as good as i hoped it would be i would keep it, theres no reason to buy the Z7 which is more expensive, but its a fact the the image quality is superior to sony
@Golan Ziv, I see, I have not shot Jpeg for over 10 years so I am not qualify to make any comments on that. I have played with both Z7 and A7R III myself quite a bit when shoot out with friends, I personally think the A7R III is in totally different league, no need to call me a Sony fanatic as I don't like Sony in general and prefer Nikon that's why I brought a D850 instead of a A7R III and also own D500 and waiting for D6, and D3 and D300 owner before and i can trace all te way back to FM2 and 8008 and F4 days......but just the focusing system, the buffer, the single card slot..... makes the A7R III so far ahead, but again I didn't like the Sony ergonomics so I decided to just stick with my old 7RII on the Sony side so I can continue to use all the Zeiss Loxia and Voigtlander primes, and went with the D850 with vertical grip on the Nikon side instead of the any Z. ,
What Nikon does, when its further away and couldn't recognise eye; could be improved over time with future firmware yes. But otherwise as long as at that distance it's recognising face, it should be good enough in most of the scenarios at that wide level, having your focus point at face is all you need, due to DOF on those focal lengths, or the distance from the subject. Remember, Dof is shallower when you are closer to the subject.
All in all, I won't consider it as a cons, as long as the feature is implemented.
That is the thing. Sony tries to impress people by constantly drawing a marker that it has recognized an eye, regardless is the whole face inside a DOF. Others will simply set eye recognition to standby when the recognized face is smaller as face size in frame is defining the DOF per format.
So why to put more resources for the eye detection if the both eyes would fall in DOF?
At this point its a close race, what means that Nikon is really doing its best to catch up. I wonder what there awser will be on the new Live Eye-AF that comes with the next Firmware update to Sony. Seeing how much they already added since the release of the Z 7 and Z 6, Nikon users know they will be in the game and can expect futher improvements! *added: I love to see both compagnies push the boundries of their systems.
The truth is that Nikon's video AF, liveview and eye AF in a single try became one of the best (Sony is probably the best yet) among FF mirrorless cameras. And that makes Nikon one of most future oriented companies. Sony will remain to be a leader in FF ML segment, but Nikon may become one of preferred choices too and with its traditionally strong DSLR segment Nikon just did what it needs to be a modern camera company.
Showing focus on screen and actually having photos with eye in focus are different things. There are times that my old Sony A7 showed that the eyes were in focus but the final images weren’t. Although happens rarely, it does happen.
Now I wonder why Nikon didn’t allow DPR to keep the photographs for analysis as mentioned in the post. Maybe it’s because of this reason?
Smaller size not always is a plus, I always keep the extension grip on my A7RIII, simply cannot use it with my pinky below the battery compartment. Other users may see it different, obviously, but the force I make with all the fingers and the stability of the camera is totally different, even more if I use big teles.
Fixing their autofocus just made Nikon a whole lot better. Would be interesting to see the result coming out of this Eye AF plus the ability to output RAW. I hope Fuji can make their magic work and make the XT3 output RAW
Good that things are getting accurate but eye AF can screw up in some multiple person shots. It doesn't know if you want the bride or groom's eye in focus.
I would consider this an uninteresting test. The subject really isn’t moving much. It’s just really a question of whether the camera can detect the eye.
So a real moving subject test like this one, and let me know how the Nikon does. (I realize this is a prerelease Nikon firmware. Here’s the prerelease Sony firmware for the A9. Neglect the 20FPS but realize this kind of detection capability is available on a $900 crop body. It’s not completely clear how much of this performance comes to the A7III as this was shot in the new tracking mode it seems. But EyeAF updates aRE coming to the A7III.)
i have the z7 and i don't see why i need the eye af. all my portraits (close up's and mid range) are extremely sharp and the eyes always sharp. have no clue how the eye detection gonna improve it
I don't believe your wide aperture, Narrow DOF have sharp eyes unless your placing your AF point on the eyeball. Or your portraits are not wide aperture. This is physics.
Sure. The lens seems amazingly fast to focus. But simply the tracking ability demonstrated in the video shows the kind of movement in subject you need to compare the currently best iteration of EyeAF with the new guys. I know DPR was very limited in what they were allowed to do. (I’m surprised Nikon even let them point a Sony at their model). But someone waving their hand in front of a basically stationary eye isn’t really a tough test anymore.
Can’t wait for this FW update even though I probably won’t buy the 135mm F1.8 lens shown here. I expect the tracking to perform very well with the 70-200.
I like that Nikon's eye AF box, by showing a triangle pointing to the eye not selected, seem to imply that the other eye can be selected via the joystick or 4 way controller. With my Sony A7ii or A6300 I am not able to manually choose the other eye on the fly.
Since I have both cameras and have tested them back to back with dozens of lenses, manufacture options, third party, adapted and native, I can tell you that in real life the Z7 trails behind the Sony.
In real life with subjects moving around toward and further from the sensor, not just horizontally along the plane of focus as demonstrated here (which is nothing spectacular, my 'old' A7R2 would have no issue holding focus with the test in the video), the 7R3 wallops the Z7.
I'd like to see how the two cameras fare with a subject/scene that will really test the performance out with an image sequence to test not what the camera says it will focus on, but what it will actually deliver.
This test with the A9 with its newest firmware would be even better, just to show how good/bad the 7R3 & Z7 are in relation to what I think is the benchmark.
Seem like a pretty consistent test to me as they are tested in concurrently in the same setting for the scenario. The test is as fair as it can be. It not extensive because z is alpha/beta mode and they won't given the chance. It will be logical that Sony will be better, but from the look of things, Nikon seem to be doing well.
Trails by how much? Quarter of a second? Half a second? A full second? Please don't say 2 seconds because I was really thinking about buying one of these.
Whilst some criticism of Nikon was warranted when the Z6 and Z7 were released it's refreshing to see Nikon refining the product and actually see tangible improvements. If the purported AF improvements are also good, the Z6 will definitely be a lot closer to the A7III other than dual cards and lack of a real battery grip option. Don't forget it counters with higher res EVF and LCD and even superior 4K and better size.
Now where are Canon's improvements for the R? Still waiting to see the eye-AF update for AF-C mode.
The Z6 EVF has a higher resolution than the A7III but is laggy according to DPR: "What you see through the viewfinder is incredibly crisp, but live view is laggy." They listed it as a 'con' on their conclusion page: 'Lower EVF refresh rate than competition from Sony/Canon'
The lag would definitely be an issue with action, but given these don't have stacked sensors I wouldn't be buying any of them if that was my specialty. It's either DSLR or A9, maybe Fuji X-T3
The viewfinder isn’t laggy. It runs at a constant 60 FPS which is slower than the competition and may be perceived as lag. Personally I ended up much preferring the Z6 to the A7iii. The Z6 maintains its high resolution at all times and for me consistency is king. The A7iii varies it’s resolution in order to keep the frame rate up so the already relatively low resolution gets even worse if there’s a lot of action.
I don’t see how anyone could prefer the A7. Not only is the resolution lower but the colours are not as nice, the magnification is lower and it is not as sharp or well corrected.
For me there was no comparison once I actually compared them. The viewfinder is very important to me (spoiled by Nikon F3HP for many many years) and the Z6 viewfinder is a major advantage and to me was easily worth the disadvantage it has in AF-C.
Yes Minolta introduced the first DSLR with IBIS - the 7D in 2004.
Sony also put IBIS in a DSLR before Olympus. It was in the first Sony DSLR - the A100 in 2006. It didn't appear in an Olympus camera until the E510 in 2007.
Sony also introduced the first FF camera with IBIS - the A900 in 2008.
People are complaining that a manufacturer doesn't offer a feature (Eye AF, IBIS or whatever) that they think should be in every camera. When the manufacturer does add this feature to their cameras, it's sad because they are just copying someone else. Damned if you do, damned if you don't.
Pointless comment, IMHO. One may say that it's sad to see Sony copying Nikon, since Nikon made cameras long before Sony bought Minolta and became a camera manufacturer. Still pointless, though.
Well said. I thin it's safe to say, anyone who says the IQ of the A7RIII is superior without having used both as you have Golan, is either lying or lying in a rubber room.
Learn to read Max. I didn't say anything about the image quality of the A7rIII versus the Z7, I disputed Golan Zivs ridiculous claim that the 'IQ of the A7RIII is not excellent'. The image quality of that camera IS excellent. Didn't mention Nikon at all.
I have no idea whether it has or not because I've never used it, but DPR in their review gave the Z7 a slightly higher score for raw image quality (vs A7rIII) and a slightly lower score vs A7rIII for jpeg quality and I've got no reason to disbelieve them. https://www.dpreview.com/reviews/nikon-z7/11 The Z7 should have slightly better IQ than the A7rIII since it has more resolution.
Id say the Nikon was the clear winner, more consistent, more accurate. The sony saw the face from farther away but in those cases the DOF is wider making little difference. Clear win for Nikon.
Clearly you didn't read my post. Yes as i said the Sony locked the eye further away but at what distances? Look at the guy behind the counter, is the DOF really thin enough to make a face lock inaccurate? Nope.
At greater distances, as i also said above, DOF is wide enough to make eye tracking not necessary. Faster lenses will offer thinner DOF but even at what, an f1 setting at that distance, the entire face will be within the focal plane.
Sony identifying an eye at such a small subject size doesn't help at all. Win Nikon.
clearly you didn't read my post, much less look at the video... sony didn't "see the face", sony saw the EYE further away, at 0:39, while Nikon did NOT see the eye, at that same distance.
obvious win for sony, Nikon eyeaf totally failed, because it is inferior.
if Nikon fails there, it will likely fail at other distances as well.
dof is irrelevant of course, because both cameras were side by side at the same distance.
Nikon seem to do better with the prioritisation of the eyes and Sony does better seeing further. If I have to choose one, I would go for the prioritisation, as eye detection becomes less useful for further way subjects where the dof will be sufficient to cover the profile length of the subject.
"Id say the Nikon was the clear winner" Well, not yet. More meaningful tests must be made to determine if Nikon is really able to match or even surpass Sony's already superior Eye AF system especially tracking the eye from a distance. However, it looks promising upon the first impression.
@rubber ducky, bc in this case the subject is human, and for their head to be so small it means they are far away, which also means thin DOF isnt the limiting factor.
At that distance the DOF of even fast lenses is sufficient to cover an entire face, not just the eyes.
Can tell you're an M43 user. Unfortunately on an A7rIII or an Z7 the 'DOF of even fast lenses' isn't at all 'sufficient to cover an entire face'. Nothing like.
Also how can achieving focus be unhelpful? Even if something is not needed that doesn't make it unhelpful.
You don't get to group me into any category. I have owned FF 3 different times, apsc even more. I have used as fast as f1.8 on FF so i have an idea what it's like to manage thin DOF. I have also used as fast as f/0.95 on MFT which offers the same DOF as f/1.9 on FF.
And portraits are what i shoot 95% of the time, so i also have an idea how those thing DOFs apply to eyes and faces. Play semantics all you want, the point is once the DOF is sufficient to cover the entire face, being able to isolate just the eye isn't necessary.
Having more accurate and consistent eye/face tracking is far more useful, and Nikon has proven more accurate and consistent than Sony's in that demonstration. Enjoy your Sonys dude, but the Nikon clearly won.
Well just from that video my impression is the Nikon seems pretty good, and in some of those sequences grabbed and held focus more stably. The Sony had a box over the eye in one case but the face was OOF for a few seconds whereas the Nikon locked on and got focus. Still will be good to see 100% crops after the shipping fw.
It’s not the Sony camera that is OOF, its the camera filming the Sony that don’t hold focus. Watch all the information on the Sony screen getting OOF as well.
What I'd like to see is a focus acquisition area on the eye, shaped like an eye, that changes shape as the profile of the eye changes (ignoring the lashes). And the same goes for faces. The higher resolution EVFs should be able to handle face or eye-shaped sprites with ease. Anyone can do a box... ; - )
Many mirrorless cameras already have eye AF. It improves with almost every iteration of model or FW.
Jim Kasson found that when DoF is too thin Sony doesn't focus on the iris, but instead the tip of the eye lash. It could be the same with other cameras too. But Sony doesn't let you adjust focus like Nikon does. So be careful with very shallow DoF.
the a7riii uses what sony calls "4d focus", which has been used in sony cameras going back to the a6000/a77ii: "Steadfast tracking Never lose sight of your subject. Our AF algorithm stays focused on the action, and even *predicts* your subject's next move, without getting distracted by any obstacles in the frame...The fourth dimension of 4D FOCUS is time, accurately *predicting* and stably tracking your subject's next move." https://www.sony.com/electronics/4d-focus-camera-settings
If the Sony is focusing on eyelashes like many people are reporting including Jim ( who has posted test results and examples), then, yes, being able to adjust focus in that situation would be a benefit.
DPR should do such torture test that a person is fast moving, fast rotating, fast jumping up/down, left/right in/out frame and quickly moving forward and backward and from some distance. Don't forget big FW 5/6 update for A9 and FW 3 for A7r III and A7 III will be released in these two months to further improve already excellent Sony eye-AF with real-time eye-AF.
https://www.youtube.com/watch?v=ww8HT_FbL1g Start at 2'29", believe still quite a gap compared to the best Sony eye-AF especially if person is fast moving or from distance.
Yep. Same reaction. Plenty of cameras (even ones with a bad reputation for focus) do a good job of keep the box around the face/eye. However, that doesn't mean the camera was able to actually focus on it.
I think Nikon is stepping into the right direction with its approach in refining its eye AF capability as a no non-sense firmware upgrade to its nascent mirrorless system to match it with Sony's instead of releasing a new cheaper model, crippled and let the marketing do its magic. lol
I guess I should not be surprised that so many seem to be angry that Nikon has shown a real improvement in AF performance. It seems that the competing brands have very productive troll farms.
Please stop with the ridiculous conspiracy theory thing. Conspiracy theories brought us Trump and that is already enough isn't it.
There is no such thing as a Sony, Nikon or Canon troll farm around here. Let's get real, how critical is it exactly to influence the bunch of old farts that makes the audience here at DPR? The answer is easy: not very much.
We are just a bunch of people arguing about my camera is better than yours because well, there is not much fun to be had around here in our old days.
@Jay-A why is that so difficult to believe that marketing troll farms exist? DPR is an Amazon subsidiary what shows up here matters > than you think. You got people making a $1k/day playing video games on youtube, that's pretty unbelievable.
Every time people mention troll farms boy, do they never point me to one. Hey I'm not picky, money's money, but these people either don't want workers or don't exist. Curious how that works.
Does that mean that Pentax has a ragingdefenders farm? That'd make more sense honestly.
@Jay-A You were partially correct, Nikon and Canon do not have a troll farm, Sony has been sighted numerous times in the gaming forums for having troll farms. So why not camera trolls?
because honestly the customer base for such cameras has shrunk to almost nothing. It would make no economical sense to maintain a herd of trolls just to influence such a small number of people. I don't know about the gaming business but it's a far bigger market so I agree everything is possible there.
The proliferation of angry trolls provokes the ironic question of their origins. I should have said " Makes one wonder if the competing brands have troll farms."
@Jay-A Your moving the goal post. You said that it was not true. I stated that Sony does in fact use troll farms as they’ve been caught numerous times in gaming forums doing just that. Why they would waste there time is not for me to answer. The point is that every time there is a Nikon article the same players come out to troll, and if they are not the same trollers, you look at the their history and you find that they just joined, and have only posted negative comments in the Nikon articles. It costs Sony pennies to pay troll farms in China.
What Nikon and Canon posters refer to as trolling is generally mockery. And it tends to be confined to the comments sections that are laxly moderated.
Sony gets trolling in its user forums. When you see a post complaining about a Sony camera that includes 'A7III' and 'A73' in the same headline so that it can be found by two different search strings you know there is professional trolling going on.
@NexLupus: I think you’re seeing stuff that doesn’t exist. I can also point you to recently joined weirdos who troll on Sony articles, too. These are just people with far too much time and money. You’ve been watching too much mission: impossible here.
Troll farms exist in China. It is a known fact. It is funny you people in the West argue about it. Just google 五毛 (literally means 50 cents) and you will see they exist.
"Troll farms exist in China...". They probably do but imagining that they go through the hassle of learning proper English in order to be able to writte in DPreview and don't sound like a Klingon needs lots of imagination...
Exactly El Diablo - Wealthy, bored American retirement home members are much more commonplace around here than Chinese trolls. People here should tolerate a bit more criticism before calling out conspiracies.
@Jay-a Why would it be a major conspiracy to point to a company that has a history of hired trolls. A company that has been caught numerous times using those underhanded tactics to negatively influence the tone in the comments section of competitor articles. Believe what you want, you are free to do so, but I will err on the side of how that company has comported itself in the past.
You've not thought this through. If Sony was astroturfing Canon for example the Canon forums would be rife with posts from bogus users complaining about how their gear failed. They are not.
Sony forums on the other hand are and have been for years.
Also established brands are not 'trolled' by market entrants. That doesn't work, because they have no clout - it's the other way round - dominant companies discredit entrants.
You could possibly argue that now Sony is dominant in FF and mirrorless they may use black marketing against Canon and Nikon but there's no sign of that happening yet.
The further you get away from a subject, the less difference there will be between achieving focus on the eye and achieving focus on the face (as DOF increases). But people who actually shoot people would know that, of course ;-)
"further away from the subject" in terms of what, exactly?
as the subject gets smaller in the frame, there are fewer ospdaf points on the subject, so af is going to be more difficult... anyone who has actually used milc would know that, of course ;-)
you can see it clearly at :49, where the Nikon z camera fails to recognize eyeaf, while the a7riii does.
@MILC, there is a point to that statement. The precision of the AF motor, the DoF and more all factor in. The fact that sony recognizes the eye further away is a good thing and I hope it correlates to the motor AF step size.
What MILC man didnt understand was as distance increases DOF is large enough that EYE-AF is not required and just focussing on the FACE will give the same result, regardless of what camera you use.
what vzlnc didn't understand is that the sony a7riii ability to utilize eyeaf better than Nikon does, at the same distance, will translate to superior eyeaf performance in most all other scenarios.
and indeed, subject recognition is what sony animal eyeaf is all about... it's the next level in eyeaf.
vzlnc: precisely. Sure, the A7 does better at recognising an eye in that demo'd situation. But the point is that in that example it wouldn't make a difference because the entire face would likely be in focus when you take a shot.
No. Even with the existing face detection, there is no need to hit the OK button.
The OK button is only to manually identify objects to track. This does not apply if the camera can automatically identify objects.
Having to push OK to manually select and deselect tracking is terrible. If you frequently track non-face or non-eye objects, I would not recommend the Z6 or Z7 until this is updated.
It is one of those features... when it exists in the camera, it may not necessarily increase sales. But when it doesn't, definitely decreases some sales - whether due to real need or just bad publicity.
I was planning to buy a camera last year but was debating between a Nikon DSLR (for the lenses and better C-AF) and the Z (lot of things to like) and the A7 (only because of the Eye-AF). Things turned another direction and I have to wait a year before I can buy a new camera but I am liking what Nikon has done in the recent weeks.
With this Eye AF and the f/2.8 lenses announced, the balance has definitely tilted towards the Z.
Satyaa the main decision is buying into a new camera SYSTEM with it's lens and flash line. In the past (film days), the life cycle of a body was about 10 years, and now it is about 2 years. And many things can be improved by software/firmware updates in existing bodies. It's a decision of marketing politics/branding of a company to keep camera bodies up to date and even improve them by new features with firmware updates (like improved eye AF). Fuji understood this.
Shutter speeds for Sony and Nikon were significantly different according to the video. Would that affect eye focus speed, accuracy and acquisition distance under these lighting conditions?
I believe the idea is that if the eye gets temporarily covered, the camera is supposed to be smart enough to predict where it still is to reduce any lag of re-acquisition once the eye becomes visible again. Ideally you won't be snapping the photo if the eye gets covered up (in most situations, anyway) so this would be a good thing.
Very similar... which I'd expect. Really good odds the algorithm behind both is literally the same, with minor differences in parameter choices. There are a lot of subsystems that are used across multiple camera brands. For example, Sony's DRO and Nikon's D-Lighting started out as the same algorithm (purchased from a 3rd company). Given the Nikons are using a Sony-built sensor, I wouldn't be at all surprised if the basic eye AF algorithm was part of the sensor deal.
I thought the same. Furthermore Sonys newest phone got eye af as well. Since Imaging Products and Mobile Communications are different subsidiaries it would make sense, that there might be some sensor+alogrithm deal.
keeponkeepingon: Because Nikon is basically copying what's been done with Sony sensors using a sensor made by Sony. Even if Sony didn't share IP for the eye AF algorithm, they certainly did share the sensor interface and reverse engineering Sony's algorithm would not be hard -- I'd bet it's a straightforward NN (or two: first find face, then eye in face) + some logic for smoothly adjusting focus. Incidentally, it does look like the Nikon version falls back to face detection faster than Sony does and also gets lost faster when the face turns... so Nikon still has some parameters to tweak -- but this is a pre-release demo.
Thank you for that explanation Prof Hank. Very interesting. It seems that algorithm development offers a new battle line along which camera companies can compete. Very much to the benefit of users and the utility of these devices. It's a great time to be a photographer.
You do realise that separate companies build and sell sensors as build and sell cameras within Sony organisation. And said company is probably not in the habit of selling years of r & d features that give them their competitive advantage to their competitors? Certainly not if they plan to be around for long. Nikon buys sensors from Sony semiconductors. In all other aspects of camera development, they are competitors. Heck , I suppose Nikon just buy the Sony cameras and re-case/rebadge a la hasellblad? According to your reasoning
I would be interested in the results of f1.4.... f2.8 is a bit easier to do. Nikon show a bit better response and the hand in front of the eye didn't confuse the AF-point. Nice job from both...
The video clearly show when camera is a far away from the model, Z7 unable to get eye but only face detection. Also this is not the extreme situation as the model didn't move fast. They should use F1.4 fast lens and test when the model is moving fast, rotating, turning backward and forward, jumping up and down, left and right out of frame and coming back...in extreme situation, and also how long distance the camera is still able to detect eyes.
@StevieF The good thing is that everyone can decide on the video... for me the Nikon was a bit more spot on.
And posting an old reference to a DSLR vs. A7II from "MILC man", which has nothing to do with *anything* in a test A7RIII vs Z7 whatsoever, shows how angry the Sonycrowd get's if they are taken down on specs ;)
@StevieF Second that. I can enjoy the fact that Nikon and maybe Canon will be soon on par with some of the Sony-features. But it seems that some Sonyusers lost their confidence on that. Maybe it's because the specs were the only reason to buy into that system and now they fall bit by bit. Literally.
@StevieF - "I have zero interest in Sony cameras so why would I even bother going into a thread about them?"
good question, why are you constantly posting to this a7riii af comparison?
is it because you feel insecure about Nikon af? that's understandable, it's clearly not up to the sony level of af, see the way that nikon fails to register eyeaf at :49, where the sony camera clearly does.
why does vscd keep trying to make false claims about it? hilarious.
@StevieF - what part of sony a7riii being in this video did you not understand? your silly comments claiming that it's a Nikon-only article indicate insecurity on your part.
your attitude is better served in the z-mount echo chamber, where you and vscd can post false information, without it being corrected, lol
for example, I notice that you keep attacking sony, while failing to address the Nikon eyeaf failure at :49, that I brought up.
yes, you certainly do a good job of that... it's because you and vscd wanted to avoid having to admit the Nikon eyeaf failure at :49
"- who cares? You do, patently, but I don’t"
another example of how you don't understand the importance and the functionality of eyeaf, and how you feel the childish need to dismiss what sony has accomplished with it... just another attack on sony.
it's sad that Nikon owners of your ilk can't admit that Nikon dropped the ball so badly with their milc development; they should have done it years ago, like sony did, maybe there wouldn't be so many former Nikon owners using sony these days... for example, a Nikon dslr owner looking at sony milc:
@StevieF - "it was only a matter of time before members of the fully paid up Sony internet band of non-entities turned up with references/links coming out of their ears - they could empty a room at a party faster than a bad smell."
your first post to this thread is a good example of your inability to engage in an adult intellectual discussion, and it proves that you feel this childish need to attack sony for no reason.
nobody cares what you like or dislike about sony; this is NOT an article asking people what they like or dislike, lol
@MILC man Where do you see a pure "Sony article"? We're not responsible for the Sony-half of the video. I see a comparision between a new cam (Z7) and and older one (A7III). And *I* personally found the Nikon to be better in *overall* (for example: with the hand in front of the eye). Live with that opinion, it's a free world. Nobody dismissed what Sony has done, but you don't loose your face if you admit that the force is strong in Nikon at the moment. It seems that you have serious problems to admit that.
the thread title clearly states "a7riii" right in it... so neither you nor StevieF gets to claim that it's just about Nikon, that is nonsense.
take your Nikon bias back to the z-mount echo chamber... you are clearly unable to admit the Nikon eyeaf failure at :49, to the point that you can't even address it, lol
@MILC man Where did I say it's a 100% Nikonarticle? It's the second time you claim something untrue like this on two different persons in this thread. It's a COMPARISION! 50/50. And I found the reaction *overall* better on the Z7. Don't worry, I don't even have a Nikon. Are you the same person as Cosinaphile, he has the same stupid answers with no arguments, getting personal very soon and ending everything with a "lol" at the end. Do you think that gives you more credit?
@vcsd - Where did I say it's a 100% sony article? It's the second time you claim something untrue... what is the "sony-half" of the video? you are posting nonsense.
see how you still can't address the Nikon eyeaf failure at :49? do you think that anyone is going to take your claims of the z7 being "*overall* better" seriously?
@MILF man Maybe we don't see what you see. The time you refer to has no comparision to the Sony, maybe the Sony would fail on this completely... we don't know. But I see that the eye is lost @0:33 on the Sony, while the AF-point sticks behind the hand on the Nikon. So, now what do you want to do with facts? I don't think that you will answer in a polite and objective way... that's the reason why nobody gives you an answer. Barfing dogs get no meat, you know. I have no bias on Nikon, never had as (mostly) Canonuser.
so at :49 in the video, you can't tell the difference between the small eyeaf square on the sony, vs. the big face detect square on the Nikon? lol, that is indeed hilarious.
if you don't know the difference between the little square and the big square, why are you even posting to this article?
or maybe it fits in with your failed claim in your first post, that "f2.8 is a bit easier", which applies to dslrs, not ospdaf, as I proved with the link that you still don't understand.
@StevieF - "it was only a matter of time before members of the fully paid up Sony internet band of non-entities turned up with references/links coming out of their ears - they could empty a room at a party faster than a bad smell."
your first post to this thread is a good example of your inability to engage in an adult intellectual discussion, and it proves that you feel this childish need to attack sony for no reason.
nobody cares what you like or dislike about sony; this is NOT an article asking people what they like or dislike, lol
@MilcMan I still see only one cam @0:49... do we have different timelines on the video? How do you know how the Sony performs in the same situation? The scenes before had no serious movement of the girl. Anyway, I guess everything was said in here. With no lol.
@StevieF I am curious as to how that Z6 has "paid for itself". Has your workflow and marketability improved so much with it or it's just a figure of speech? lol I think in this particular test both cameras perform ~ the same but the Z6 is much more camera than the Sony a7III. Between those two the Z6 choice is clear. However, at the moment I am salivating over a used a9 for action to add to the D850 for everything else.
@vscd - it's actually at :39, not :49, but the fact that you couldn't tell the difference between the big square and the little square at :39 just proves my point, lol
the z7 ($3400) clearly has inferior af to the a7riii ($2800)… classic Nikon marketing; pay more, get less, but oh that's o.k. because it's a Nikon.
@MILC MAN So, you nag on 2 people for hours, getting personal with no reason and after all that you kind of admit that you are *WRONG* all night long with the timeline and don't even have the guts to say sorry. After that you jump right over to a totally unrelated topic like the price to deviate from beeing such a, sorry, moron all the time? That's priceless.
We never spoke about square and little square because we never spoke about "0:39" until now... but you know, the good thing is you manifested yourself in the Internet with all your glory. I really think you are a fake-account of "cosinaphile" which does totally the same all night long.
@vscd - I see that you are still failing to understand the difference between the little square and the big square, lol
or is it just that you aren't capable of admitting that you were wrong to have not seen the z7 failing to acquire eyeaf at :39... while other people did see Nikon fail there, and they commented about it: "The video clearly show when camera is a far away from the model, Z7 unable to get eye but only face detection."
calling me names isn't going to change any of that, lol
Sometimes I see a commercial that is soooo annoying that I would never buy that product! MILC man does the same for Sony. Annoying like a neighbours little dog that just barks all day for no reason!
"The video clearly show when camera is a far away from the model, Z7 unable to get eye but only face detection." When the subject is far the depth of field is more than enough to only need the face to make a very fine focus. Sony's system is actually more powerful but does not bring anything in these conditions.
@Nikonb - "When the subject is far the depth of field is more than enough to only need the face to make a very fine focus."
if Nikon eyeaf fails there, it will also be weaker at closer distances.
not sure why it's so hard for Nikon owners to understand that... I guess it's because they don't have any experience with eyeaf, and their platform fanaticism demands that they make excuses for inferior performance.
@MILC Sony must be shaking... Nikon Z6 already has a better viewfinder, better build, better screen, better 4K, better weather sealing, better ergonomics, better menu system. After the upcoming firmware upgrade, Nikon will have CFExpress, eye focus, Raw 4K, improved focus tracking. So after the firmware upgrade, any possible reason/argument to buy a Sony will be gone!!!!
@MILC I ONLY have 1 account MILC (ONE)...I don't need to hide behind multiple accounts like you and your fellow SONY employees do. So you are saying that you don't post on Nikon only articles? That is a bold face lie and absolutely demolishes any credibility you may have.
@NexLupus - sony is laughing, and so are sony owners.
z-mount doesn't have any lenses, and the 4k output is useless because Nikon doesn't have any video lenses, even in f-mount; Nikon was never a video company, and now they are pretending to do video.
z-mount has banding issues, laggy viewfinder, no screw-drive af support, no Nikon milc crop format, simply awful af-c performance, and now weak eyeaf.
and learn how to read "sony a7riii" before you post next time, lol
@MILC Everyone and their mom has already shown that the 4K on the Nikon is superior...Even DPReview showed this in their video roundup. The sad thing is you are correct, Nikon never was a video company and in it's first iteration of mirrorless, has absolutely demolished the SONY's.... Nikon can mount over 300 lenses, and with the adaptor can use 98 lenses with native performance...you know, lenses like the 500, 600, 800, 200-500, 20 1.8, 28 1.4, 19PC, 60 Micro, 180-400, 85PC etc, etc...non of which Sony makes.
@NexLupus - you have obviously never shot video, or you would know that video lenses have specific parameters that still camera lenses do not have to match.
Nikon as a company has no video history, so they know nothing about video, and that is proven by the fact that Nikon has no history of making video-centric lenses.
it's unfortunate that you refuse to understand actual facts like that, but such is the nature of platform fanaticism.
@MILC OK Bro, you keep telling yourself that... Especially considering every review showing the Nikon smoking the Sony in 4K... For a company that doesn't know anything about video, Nikon sure is faking it really well ;)
@ PWTphotography At least Nikon has a 500 that I can mount onto the Z6/Z7. You should take a look at the 500PF 5.6, it mutes beautifully with the Nikon Z cameras. Too bad Sony doesn't have anything like that.
@MILC LOL, Nikon can also mount the Sony video lenses with an adaptor...So I guess there is no advantage to Sony video after all!!!! God, you Sony shills are so dumb...
@NexLupus yes such 500mm on Z7 only good for shooting static birds. I also can mount Sigma 500/4.0 OS Sport on A9 via MC-11 that is in a different league and AF-C tracking basically is quasi native and can shoot 15fps at the same cost actually as 500 PF.
@MILC Dude, you were just talking about using Nikon 500pf cause Sony doesn't have any of the lenses I posted about...you even linked to a Fred Miranda post. Pot calling the kettle black much?
@MILC I notice that you completely ignored my point about YOU posting a Fred Miranda article about Sony shooters using Nikon lenses on Sony cameras... To your other points; it is true that Nikon does not have Cine lenses, it is also true that most people that use Sony cameras for video (99.9999% maybe) do not use Cine lenses on the Sony's. It is also true, that the Nikon Z cameras will now take the Canon, Sony, Leica Cine lenses, with adaptors. Something Sony users have been doing for years and continue to need to do since they still do not have the breadth of lenses that a real camera manufacturer like Nikon has, as YOU pointed out by linking that article...thanks BTW.
@MILC TROLL I also noticed that you did not comment on my point (earlier) about you trolling Nikon only articles in the past. As far as BIF, here is an article by renowned wildlife shooter using the 500/4 and 200-500, (both lenses Sony does not make) that compares it against the D850 and D500; he noted that it wasn't quite as good as his D850/500 but it was not far off once dialed in...so far better than PWT claims. https://www.youtube.com/watch?v=DQFPjvIBQfE With regards to bro, dude etc, I will no longer give you the benefit of the doubt, and will now only refer to you as TROLL.
@NexLupus - calling me names just puts you in good company, with the rest of the fake accounts.
you still don't get anything that's been said here... for example, shooting video isn't just about cine lenses, because most video event work is done with powered parfocal zooms, which Nikon has ZERO experience with.
and no, you don't have anything valid to say wrt the fredmiranda link, for all of the obvious reasons.
Seriously, I wish all mirrorless brands would include a menu option that allowed the photographer to *choose* the colour and brightness of the focus indicator.
I find little bright green boxes flashing all over the screen to be quite distracting!
Interesting first comparison, and Eye-AF as incredible potential for some of my use-case, if coupled with fast and precise focusing, including non-static portraits.
When I am doing portraiture at f/2.8 or even f/2 w/ FF and 85mm, with a shallow depth-of-field, it's extremely hard to be exactly in-focus by hand and even classical AF don't work as precisely as-needed when people is moving, turning their heads, laughing while advancing it, etc.
What is a non-static portrait? I have been shooting portraits for over 20 years an I do not remember ever running into a non-static portrait. If they are moving around at an event it is a candid shot and using Eye AF would be a joke for that.
