Wasn’t there some sort of announcement from Sony toward that last week of October?

Mike Sandman: Interesting to total the results by company -- Fuji 13%, Nikon 28.7%, Sony 35.3, Sigma 6.9% etc. Of course the choices on the voting list were selected by dPreview's editors, but it's still notable that Canon is absent.

Thanks for the correction! It makes the results that much more interesting.

Superb story, video, and videography on top of the bison images. Thank you.

A month ago during a snowstorm in Boston, I went out for a walk along the marshy Muddy River with a 70-200mm lens. There, lying the snow, was a photographer dressed in camo with what looked like a 600mm lens. He was focusing on waterbirds swimming on the river. He was there when I started my walk and still there two hours later in the same position, the snow an inch or so deeper around him. That kind of dedication is instructional and inspiring. And a little daunting.

"Buttons and dials still need more feedback, especially with gloves"
???????????

And now that I actually have the camera and used it with gloves in a snowstorm... I agree about the AF-ON button in particular.

Thanks for including a "best accessory" pick. The Godox flash is a deserving winner, and it has a twin, the FlashPoint Zoom Li-on sold by Adorama.

In reply to:

Iloveaircraftnoise: Just out of curiosity I'd like to ask the Sony shooters out there what it's like to handle the A7 series cameras when shooting all day events and functions with, say, a 70-200.

Is it ok? Is it front heavy? Other than a quick play around at the store I have no experience handling this sort of combo.

The OP asked for comments on what it's like to handle the a7 cameras with a 70-200 mounted. Reasonable question, which I hope I answered reasonably. No quarrel here with anyone who's happy with some other camera.

Spent four hours at an event yesterday hand-holding an a7 series plus a Sony 70-2-- and was quite comfortable.

In reply to:

entoman: It's utterly pointless arguing whether the D850 or a7Riii is "best". The differences in specifications and performance have now reached the stage where they are negligible.

But there is a huge difference in the way they handle. Some people like EVFs and a compact design, others like OVFs and traditional DSLR ergonomics and will buy accordingly.

Both cameras have negative aspects (e.g. the mirror clatter and blackout between frames on the Nikon, and the more fiddly controls and menus on the Sony). These will be the deciding factors, not the specs or performance.

Will Nikon fans switch to Sony? Unlikely.
Will Sony fans switch to Nikon? Unlikely.
Canon fans continue to wait, and pray.

entoman -- Check your assumptions, sonny. I'm 74 and just bought an alpha 7R iii, a follow-on to the alpha 7R ii I bought in 2015, when I switched from Canon. :-)

sts2: Surprising, but good choice. Battery life is one of the most significant drawbacks of mirrorless cameras (i.e. a dealbreaker for many), and this upgrade helped Sony close the gap with DSLRs in terms of usability/reliability big time.
This battery is more of a "game changer" than the entire A9, dare I say.

This is true. A battery with 650 shots in it's belly isn't going to last as long as a DSLR barely with three times that many. Everything has its tradeoffs. The D850 is a superb tool for photography, as is the a7Riii. Each has its strengths and weaknesses, and if you already have a D850 you'd be nuts to think about switching. Enjoy the Nikon in peace.

I'm an amateur, not a pro, and the a7Rii's short battery life was a PITA. I carry 2 spares, but batteries choose to die just when you're about to take a good but fleeting shot. And the spares lose charge sitting on the shelf. (I know that will still happen, but from a higher level of capacity.) A battery upgrade was a necessary condition for me to switch to an 7Riii.

But most of these comments miss the point Richard is making -- when you compare the Nikon D850 and the Sony a7Rii, the mirrorless vs. pentaprism distinction is altered. A battery that narrows the overall performance distinction MILCs and DSLRs and focuses attention on the things that matter to the image, like focus speed and dynamic range.

Mike Sandman: Question: On the a9 and so presumably on the a7Riii, DRO (digital range optimization does the following: "By dividing the image into small areas, the product analyzes the contrast of light and shadow between the subject and the background, and creates an image with the optimal brightness and gradation."

The a7Riii has hybrid log gamma HGL available for stills. The a9 doesn't have that capability. How do DRO and HLG interact? Does HGL replace DRO? Supplement it?

Randomguy, thanks -- it took me a bit of time to figure out what you meant, but I got it.

HGL is applied to Picture Profiles, so DRO would have to be turned off. HGL is available for both movies and stills, just as the review says. It's covered in the User Guide, which can be downloaded from the Sony Australia support site, even from the US. Several pre-set HGL profiles are available for movies and one profile is available for stills. Some aspects of the HGL setting do not apply when you're shooting RAW - Black Level, Black Gamma, Knee and
Color Depth. (Being a stills person and not a video person, I have no idea what "knee" is. )

The URL to get both the printed user manual that comes with the camera and the downloadable and much more detailed online user guide is: http://www.sony.com.au/electronics/support/e-mount-body-ilce7-series/ilce-7rm3#manuals. Sony's US support site has not yet posted these files. Perhaps they're being revised for the US market.

Hmmm... I handled an a7Riii at the introduction at Photo Expo in NY City, and OK, I didn't put gloves on inside the Javits Convention Center, but the controls were far more responsive and easy to use by feel than my a7Rii controls. I think the review is really scratching here for things that are "cons".

I do agree that backlit control buttons would be a very nice feature, like the Nikon D850 has.

In reply to:

elementare: At this point I think that it's quite hard for both Canon and Nikon to release a FF mirrorless camera. By this time they aren't in the position of neither being able to project a so technologically advanced camera without taking away resources from FF dslr cameras. Canon's mirrorless apsc is a good example of how Canon put the same sensor inside mirrorless and dslr but crop a lot of functions of the first.

And they aren't in the position of being able to release FF mirrorless unable to compete with mirrorless cameras like Sony A7RIII without collapse themselves. It's quite obvious that none is going to buy a Canon or Nikon FF mirrorless with a new mount that it's not able to match a Sony A7RIII like this.

At this point they have two possibilities, release just some aps-c mirrorless for amateur and enthusiast market (as Canon is already doing) or convert the whole pro dslr FF production into a pro FF mirrorless one, something I think it's never going to happen.

The OP presents an example of a principle that was described by James Utterback of MIT in "Mastering the Dynamics of Innovation." Process innovation (like improvement in a DSLR) usually comes comes from within the industry. Product innovation often originates within the industry, but it's brought to market by outsiders.

Incumbents are concerned about having to write off their existing investments, and they fear "eating their own lunch," failing to see that others will eat it for them. Mirrorless high-end cameras are an example. Producing competitive FF pro-level mirrorless is not in the DNA of Canon or Nikon.

ewelch: And you don't even bother to address weather sealing? At least in a way to track it down without reading the whole thing. That is what's keeping me away from Sony. My Canon 1Dx and Olympus OMD E-M1 Mark II make Sony look like a toy because of this one issue.

Perhaps there is a place in the for a third party to offer upgraded sealing with proper gaskets for the various weak links in Sony's (and others') weather sealing.

In reply to:

Mike Sandman: Until the a7Riii was released, I hadn't heard about the star eater phenomenon. And now that I've heard, I am...confused.
Page 129 of the A9 manual says:
"Long Exposure NR On: Activates noise reduction for the same duration that the shutter is open...
"Off: Does not activate noise reduction..."
And then it goes on to explain situation in which long exposure NR will not be applied.
Page 179 of the a7r2 manual says much the same thing.

Are you folks saying that even when Long Exposure NR is turned off, it comes back on with exposures of 4 sec. or longer? If so, I agree with the many posters who think that's a bug, not feature. But if you can turn off long exposure NR in the menu, well then, do it.

Further explanation welcome, but please be gentle. I confess to not being up to speed on this matter.

Thanks, sharkmelly & Victor -- Now I understand why everyone is so upset (to put it mildly). Sony is screwing with our RAW files, there's no way to block that action via the menu, and as a matter of principle, RAW files are not meant to be screwed with. I'm primarily a landscape and architecture photographer, so it will probably never matter to me, but the upset is understandable.

Thanks - LoneySpeck's explanation and the links in his blog are helpful, although it's still not clear to me whether the problem occurs with all exposures of 4 seconds or longer, or just those made in bulb mode.

If the star eater phenomenon was introduced as a result of an early firmware update meant to solve a larger problem with hot pixels, it may be that Sony hasn't figured out how to fix this it without having the earlier problem recur.
