M1963: Three articles on the Sony Alpha 7R II in four days. Not quite sure what to think of it.
"Stalking a commenter"
I am not stalking him. I have seen him around for several years trolling. He has been posting the same anti-Sony distribute since he bought K10D 10 years ago. He in fact was once banned from Sony DSLR forum back in the old days (long before we had forum moderators). He is a classic Pentax troll. I remember him; I am not stalking him.
CaMeRa QuEsT: Didn't an editor from DP previously wrote that it was site policy not to report on rumors? Is this some kind of paid Fujifilm survey concealed as news/rumor/what have you? What is going on here?
Never heard anything like that. You are making up stuff.
DPR will not report on rumors if they are under NDA about specific future camera. If not, sure they can report rumors.
D200_4me: I just wish m4/3 as well as Fuji would get off the recycling the same old sensors game. We don't need a brand new sensor every year, but every two or three years would be a nice time-frame for improving the sensor specs (better high ISO and dynamic range is all that I'd care about...I'm happy with anything between 16 and 24MP..
X-Trans is not a sensor. It's color filter. The Fuji sensor is the same 16 MP Sony sensor, but with X-Trans color filter.
rgralak: Could it be that the Sigma Art lens is not the best choice for DSLR testing? I just tried repeating the test with a Nikon 28mm F1.8G on my D810 and, using group focus mode, it was able to shoot 3FPS in continuous CL-mode and about 5fps in CH mode. Focus looked good in the shots as I moved closer to my target.
This seems totally contradictory to your added clip using the D810 at the end. You may want to double check the D810 focus settings and that you had the dial knob set to CL or CH when shooting.
Read the comments. They tested many other lenses besides Sigma.
AKH: I have been following Dpreview for around 15 years now and I don't like how it has changed over time. It is like the reviewers have become sort of fan-boys in their reviews. Just a few years ago the reviews were much more objective and balanced in my opinion.
Also I'd say that I never had any focusing issues with my D810 with fast primes down to f/1.4 and the new f/1.8 series from Nikon. Didn't even have to fine tune any of my lenses which was not the case with my previous camera the D800.
AKH "Sony A7s regarding high ISO performance even though it was less than 1/3 of a stop better than Nikon Df and D3"
Wrong, AKH. A7s was not 1/3 stop better than Nikon D4 in video mode. It was like 2 stop better. The difference was huge, and those who were making these high ISO statements about A7s were all video guys, and they were right. You are wrong.
"so those who don't buy sony product,a re troll. "
That's not what I said. You have a history of posting similar anti-Sony diatrible since the day you bought K10D many many years ago (10? years). You were also banned for Sony DSLR forum many years ago for trolling.
You are a classic Pentax troll who has been posting these rants for past 10 years.
I know because I have seen you around
bovverwonder: Does the eye detection work when using the Metabones adaptor?
Roland Schulz: Ok folks, nice test, but not completely honest: The Sony may beat Nikon´s or Canon´s best AF systems in low light using a F1.4 lens, but that´s only half the truth for wedding photographers that often take F2.8 zooms or even F4.0 to be more versatile. I bet Nikon and even Canon run´s smoking circles around the Sony using F4.0 zooms – why? Simply because common dSLR phase detect AF systems work with an internal let´s say F8 AF system, result is that lenses up to F8 doesn´t alter the AF performance. Not so with the Sony, here the AF system hitting light is limited only by the lens, but a hefty F5.6 500mm telezoom would influence the AF by 4 stops where Nikon and Canon work as before. This fact wasn´t “pronounced” in this video. So maybe the A7RII´s AF is not the holy grail for some (many) folks. Would really be nice to see a comparison with F4 lenses!!
On the other hand on sensor AF has many advantages as described, compared to dSLRs there will hardly be a front-/backfocus.
"that there is no SEL 24-70 or 70-200 2.8 yet and because of the narrow E-Mount there will probably never be."
That's nonsense. Sure there can 70-200 2.8 on E-mount. It would be larger than F4 lens, but there definitely can be 70-200 2.8 on E-mount. There is no technical problems with the mount. In fact 70-200 F2.8 A mount version works just fine with LAEA3 adapter which is simply a hollow tube.
jonny1976 is a long time Pentax troll with a history of similar posts going back 6 years.
sdchew: I wonder if the Nikon and Canon cameras will have better AF performance if a native lens (e.g. Nikon/Canon) was used.
No as Sigma tested is a NATIVE fast focusing lens
Plus other lenses were tested too.
indusbreed: This dude tested the A7r II AND is trashing its auto focus in low light. The trick being that it is using the focus assists beam to focus in low light. If you disable that, it becomes pretty much useless.https://www.youtube.com/watch?v=XxxKAJtBnhA
He is using F4 lens. DPR article is talking about performance with faster lenses (F2 and faster) where A7RII's AF is same or better in lowlight than top DSLRs.
aftab: Rishi, you know well that you have drawn a broad conclusion based on one test using a specific lens and aperture. To draw such a conclusion you need to use variety of lenses, different bodies, different FLs and subjects etc. At the end you may be proven to be right though, but for now your conclusion applies only to this specific situation.
Many other lenses were tested, according to Rishi comments.
"but a hefty F5.6 500mm telezoom would influence the AF by 4 stops where Nikon and Canon work as before"
That's not true. AF will suffer on a DSLR too. A F4 lens will AF better than F5.6 lens on a DSLR in lowlight.
nikheat: Yes, but still no mirrorless A-mount!!!!!!!!!!!!!!!!!!
MacroBokeh, K01 did not have on sensor PDAF and AF was not better than a DSLR in live view of the time. There was no EVF, no tilting screen. Ergonomics were bad.
The hate had nothing to do with looks. Read the K01 review.
Lightcapture: With bright lens. Yes. That's good. Tony Northrup did a 70-200 native lens low light continuous AF shootouts with the Canon 5DS and the Nikon 810 (I think as well), and the conditions wasn't as dim as what Rishi was testing in the video shown above. And we saw the Sony did really badly in that test. I know the lens they use isn't the fast lens, but why could the same native lenses under bright outdoor conditions did so well for Sony (which significantly outperforms its competitors) while indoors it's the complete opposite?
"Knowing the geeky Tony (not as geeky as Rishi granted), he'll shoot them in the same aperture even if one lens is faster than the other."
That's not how AF works on a DSLR. Even if you use F4 on a dSLR, the lens will open to F2.8 to AF and step down to F4 to take a shot.
Besides, read this DSPR article. A7RII apparently needs light (or bright lens) otherwise it switches to CDAF only.
57even: Actually looks like a nice bit of industrial design, particularly the switches and buttons.
I didn't realise the camera wasn't weather sealed. A little surprised at that for a landscape/outdoor camera.
Digimat post was reasonable. Yours was not. That's because you are a M4/3 troll who has a history of posting nonsense with several accounts (includes banned accounts like Everdog, JustHavingFun, etc and several other active accounts that aren't banned).
A7R is weather resistant.
Operator: Compare it with the PSP tear down:https://www.ifixit.com/Teardown/PSP+1000+Teardown/1234
IMHO the A7r II is consumer class electronic sold for a premium price. Not built to last.
A7R had magnesium shell
Long story short, A7RII is weather resistant. That's official specs of the camera, regardless of what a M4/3 troll claims.
Funny I have never seen any Pentax camera with IP rating, but they are all called WR by DPreview
Typical M4/3 troll (and yes, he is everdog sock puppet).
A7RII is dust and moisture resistant. That's official specs of the camera.
I looked at his guy's history (bluevellet ) and he appears to be just another sock puppet of old m4/3 troll called Everdog , Just_Having_Fun.
This by the way isn't his only account.
