matthew saville: Continuous red illumination of all AF points within the camera’s Intelligent Viewfinder II.

STOP THE PRESS OMG.

OK in all seriousness, the most exciting thing about this whole announcement is that they are finally actually mentioning dynamic range improvements in their press release. And if ADC is now on-sensor, they do stand a chance at a solid 1-2 EV worth of shadow noise improvement.

Hopefully, Canon won't....pull a Canon, and withold such a "flagship feature" as on-sensor ADC from anything but a 1-series for ~3 generations before letting it trickle down. *cough* 5-series AF *cough*

And the only evidence I have seen that the issue is a component issue are blogs.

Control motors only being able to control accurately in on direction does not make sense to me and I have seen no real evidence that that is the case.

But i know that modern companies try to minimise the number of components they have to hold and differentiate their products by downgrading (often in software) features to protect higher models.
That's a much better fit explanation (for me) based on the info I have seen.

Bloggers/authors have the same info that is available to me an you if we look for it.
The really good ones, like Thom notice little factoids from the public sources, apply some analysis, deduction and interpolation and come up with what to a lot of people appears to be definitive info.

That then gets cross propagated around the blogs and then filters out to the forums as lore.

The example of the knowledge base article above shows that even internal sources don't actually necessarily know how the features work or it's capabilities, let alone why it is different from one model to another.

What I am saying is that I don't find statements on blogs by themselves to be persuasive evidence unless they make sense to me or they have experiments to back them up or identify the source - e.g. "an engineer in Nikon's blah team told...".

They need to be taken as possible truth and they need to be critically analysed.

@Mathew Saville - same with me. I read a lot of blogs including Thom's, scour through manuals, knowledge base articles etc.

I've seen Thom (and others) make comments about the aperture arm, but I haven't seen actual evidence that is physical as opposed to a software feature - quote from a Nikon engineer or product manager images of two different components from disassembled bodies or the like.

I've seen a Nikon knowledge base article stating that Power Aperture allows 1/8th instead of 1/3rd stop aperture adjustments, but I have not seen anything definitive that attributes that to hardware rather than software or that the motors can only control in one direction with accuracy - that actually sounds absurd from my (limited) understanding of electric motors.

The article also says that Power Aperture can be used when recording via HDMI but not in camera
Which is incorrect - at least on my D750

armandino: I was really hoping to see innovation from the D5 and 1DXII. We will have to see the performance in the field, but such incremental changes. To me this was the time to show off some significant new trades, the next generation will be too late. This segment will become even more niche than what it is right now. DSLRs are doomed before the next generation of these cameras will be out. Only the most demanding photographers for ruggedness and AF speed will need such monsters. But even these features will not be domain of this elite of dinosaurs for very long.

@photomedium:
If no one else, science and medicine still value stills for sports (medicine, science) and wildlife (science).
In any case sport and wildlife stills are probably more extensively used now than ever before - the web allows for more images to be presented than the one or two you'd see in a news paper or the 5-6 you'd see in a magazine article.

The big, reliable fast cameras are also used by organisations such as the military and police for documentation of events and operations.

@Matthew Saville - I did google you - I assume you're the photographer not the motion picture guy? If so nice site and lovely work.

I've bookmarked your site and I look forward to our E -lens reviews. It surprises me that people have been complaining about the LV aperture issue in the lower end bodies for so long and yet I have not seen a clarification about the E lens aperture behaviour in LV.

Re the aperture arm without actually controlling it we don't know how the arm works - we can see it spring back in one direction but that does not mean it can't also be controlled under different circumstances. e.g. when power is applied and the camera is in some specific state.

Well it's said the aperture control in LV is a mechanical limitation.
I haven't seen any real evidence of that.
After all the mechanism has the required power to actually open and hold the aperture open for however long in LV and to adjust the aperture, so it kinda sounds like a control/software matter, primae facie rather than a mechanical one.

I do understand that the mechanical aperture has been a limitation for fast stills shooting - Nikon have stated that.
I would like to see any evidence you have re the LV issue being mechanical though if you know of any because it does interest me.

Also like I'd like to see any evidence either way about how the E lenses work re LV aperture on lower end models if you happen to now of any - I think that will be kinda telling.

And the other stuff I mentioned proved my point.
Nikon do gimp their lower end cameras to protect the high end.

None of the examples are particularly obscure nor were they particularly difficult to come up with.

Sound like awesome lenes - really good that Sony is stating the resolution they are designing for - I have not seen this mentioned by any of the usual suspects.

But it also looks like what a lot of people have been saying/speculating is now confirmed.
Once you put fast zooms on, and a couple of batteries any size and weight saving is minimal.

Also interesting Sony hasn't gone the Zeiss branding route.
I assume that means that optically they think these lenses are on or near par with Zeiss - I gather the t* is worth the license fee?

I guess mirrorless is "there", now.

In reply to:

Joed700: Okay, it's great to see something new from Canon. However, the fact that there is no mention of improvement in DR worries me. Also, this baby is $500 less that the Nikon D5 confirms my suspicion...Canon usually charge way more than Nikon....

@Ssantana - No one has said "I'm an X therefore you should listen to me".
Why should we listen to you?
Because you work "next to" a photographer? What does that mean? Security guard? Drinks vendor?
No gallery, no link to site in your profile. If you want to talk about chops show us your work.

Re Rishi's point.
Using a single piece of evidence that records a single instance to support a general point IS bad argument or science.
Try doing a google image search for "Sports photographer" to get a more representative view.

Re your point:
Anyway good photographer would realise that white relfects light and black absorbs it - white is therefore easy to see and black hard.

There are at least 10 Nikon lenses in that image BTW.
So it's actually easy to see the Nikon lenses in that forrest of Canons.

They're harder to see because they're black (and you need to look).

I guess the shot was taken with a Canon camera.
Poor DR - makes it hard to see detail in the shadows.
:-)

And oh yeah incomprehensibly not being able to change apertures in LV. Again possibly a hardware issue but that doesn't seem all that likely to me.
And now we have E lenses it's still not clear to me if say a D3300 can adjust aperture in LV.
I'd have to imagine it Nikon would crow about it if they were allowing that.

@Mathew - Off the top of my head 1/4000 shutter speeds, bracketing limitations,display in viewfinder electronic level disabled on 1 axis, though it works in two and even displays in two if you hold that camera at a 45 degree angle, disabled focus modes, less groups in flash commander functions,OK button won't zoom to point of focus to check focus.
Nearly of this is with the possible exception of shutter speed is software, and it probably takes more effort to go through the code and change the conditionals that turn it off.

Not metering on AI lenses I think is reasonable - there is a cost there lower, but turning off software features.

Re video Canon had too got to 1080 for the exact same reason they need to go to 4k in their DSLRs - because if they don't people will ask and someone else will. Not really kudos worthy.
Kudos to Nikon for introducing video - all after that was just incremental inevitable upgrades once the computation allowed.

Arbitrary disabling of features, subtle crippling... as a Nikon user I'd call that "pulling a Nikon".

The grass is always greener and all that.
:-)

I think Nikon are more generous with features than Canon (built in intervalometer anyone)?
But Nikon still do the subtle sabotaging etc.

Do you people mean DR or do you mean ISO invariance?

On article Yongnuo announces YN360 LED light wand (25 comments in total)
In reply to:

left eye: As there are warm-white LEDs and cold blue-white LEDs, wouldn't it have been better to use them instead of crude RGB? Start near the white temperatures you need.

RGB LEDs are known to shift over time in their temperature, and surely mixing such bright colours will be less subtle than mixing warm-white and cold-white LEDs?

Also mixing between bright white warm/cold LEDs would give much more light output than mixing RGB LEDs.

Seems like they are just re-appropriating an existing 'mood' LED bank, rather than designing a new bank of white variant LEDs for photographic purpose.

It's uses different colour temp "white" LEDs. As well as RGB:
"it is equipped with 160 LEDs designed to match daylight, 160 LEDs to match tungsten lighting and 40 further LEDs that are RGB SMD lamps."

Marksphoto: Yong needs to make a transmitter for this light , it would be very usefull for mirrorless cameras so that the light turns on when the shutter is half pressed. That would be revolutionary .

Why only mirrorless? Just curious.

White balance looks a bit out.
Of all the audience's not to check your white balance for I can't think of many that that would be worse than the DPR crowd.

On the content itself - it's like wow I've been prejudiced all my life - I guess most others are too.

On the question of exploitation - how much benefit do the individuals or homeless ppl as a class get?

If you want to shed the exploitative label then tell us what the subjects get out of the series, either as individuals or as a class.

There's no information about the subject and their stories of how they got where they are on Aaron's project page or as far as I can see any links to anywhere else with that info, so it really doesn't seem to draw attention to the subjects and their stories.

So yes it *appears* exploitative. If Aaron wants to dispel that he needs to tell us why it is not, because primae facie it is exploitative. The benefit the subjects get is not (based on the project info) proportional on what Aaron gets.

In reply to:

John Barkley: On the D5 and D500, does anyone know if there is a "focus peaking" function on the LCD in video mode? Sorry if this is posted, I can't find it.

@Deliverator - I don't see the recording of zooming as a problem (once you know about it) - it can be used as a creative effect at times, but it has it's down side for live use as a focus aid.

In reply to:

Muskokaphotog: The new Nikons are unquestionably great cameras. Apart from "professionals", who uses anyone of these cameras enough to justify spending the extra $? The other issue is the lenses. I have been using cameras and lenses for over 40 years and I think lens quality has actually regressed at the professional end. Sure we have better AF, but most lenses now need serious computer rejigging to compensate for distortions and other aberrations. When will Nikon create a standard lens with the corner to corner sharpness and a distortion free horizon?

I think you are both remembering through rose coloured glasses.
I look at old photos now - not amateur photos, but photos from books or magazines etc, and see chromatic aberation, distortion, blurriness etc etc.

Not saying there might not have been some great lenses - and frankly I don't have the experience from then to know.

But looking at the majority of the images from back then, I'd say the majority of lenses were not as good.

@Deliverator - yes you can, but if you zoom in in LV when recording the recording will be that crop - at least that's the case when you're recording from the HDMI port on a D750.

Aroart: I find it rather amusing how many photographers think there so artistic and creative when most take snap shots with high end gear and mess around in photo shop a little ... Its funny how they say there telling a story when all there doing is documenting an event.. Von Wong is a true artistic photographer his images are worthy of fantasy art and graphic novel covers..

I find it amusing you have "art" in your handle and no URL or galleries, and apparently no idea of what art is.

Von Wong is creative and this work is artistic but the message about shark's is coarse and I don't think particulalry great as visual art (but who am I? No one right? YMMV).

The value is for a company that want's to produce an difficult to produce image they know they can go to VonWong and say, here's $200,000 please make us a photo like this and he will.

His value is as a determined problem solver with the judgement to be able to assess the possible from the currently not possible, and the engineering and people skills to then get it done safely.
That's where my admiration for Von Wong comes from.
Not sure if he is a commercial photographer in the traditional sense, but it you want companies to give you $100Ks that's what it takes.
Epic image engineer. His words. Technician? for sure.
Artist? - all photographers are.
