Photons to Photos test: Sony A7rIII Dynamic Range increased by max 0,4 stops over the A7rII

Photons by Photos measured the Sony A7rIII Dynamic Range and the conclusion is:

1) At low ISO up to ISO 400 the new Sony A7rII has the edge over the A7rII. From ISO 800 there is virtually no difference between the two
2) The max measured difference is 0,4 stops

We are far off Sony’s claim of one stop advantage over the A7rII. But let’s forget Sony’s claim and focus on this fact: The A7rII already had a world-class leading DR performance unmatched by most of the FF cameras on the market. So having a near half stop increase is a nice achievement. And I expect the A7rIII to lead the DxOranking once it gets tested!

UPDATE: It also beats the D850 when it comes to overall performance:

Dpreview published the full Sony A7rIII review: “easily Sony’s best camera yet, and one of the best cameras we’ve ever tested”

Dpreview published the full Sony A7rIII test and the camera earned a 90% score. The conclusion:

The sheer capability of the Sony a7R III is hard to overstate. With the sports-oriented a9, Sony was aiming for outright speed; the a7R III has inherited much of that, but offers far more resolution and dynamic range. Like the Nikon D850, the a7R III is a camera that you can shoot just about anything with, from landscapes to fast action.

There is a vast number of small improvements and refinements in the a7R III. From the ergonomics to the better organized menus, this is the most usable and engaging a7-series camera yet. The on-sensor autofocus system needs some work in terms of subject tracking, but in other autofocus modes, the a7R III makes it dead easy to get the most out of the 42.4MP of resolution it offers. Never before has shooting such high resolution files been so fun, or so painless.

The a7R III still can’t quite match the feeling of immediacy that comes with using a high-end DSLR; the card write speeds can get in your way, and the learning curve for new users can be steep. But the fact remains that the a7R III is capable of gorgeous still images and video, and has the feel of an impressively polished product. In our opinion, this is easily Sony’s best camera yet, and one of the best cameras we’ve ever tested. It’s the most well-rounded mirrorless camera on the market today, and for that, it earns our highest award.

Pixel Shift A7rIII tests by Hugh Brownstone, Kevin Raber and Eddy Hagen.

Kevin Raber from Luminous Landscape tested the new A7rIII Pixel Shift function:

I did a lot of pixel peeping at 200% and 300%, doing side by sides in Photoshop. You can see differences when looking close. These become evident in highlight and specular areas as well as parts of an image with fine detail. There is less stair-stepping and other artifacts, which results in a cleaner file. So, while it may still be the same size as the original file, the resulting file has more perceived detail. I see this in areas of texture, such as the metal on the engine in the above samples or on the Chevy logo on the red truck.

Eddy Hagen also made a Pixel Shift test:

You could say that – at least in some situations – you get four times as much information, so comparable to a 168-megapixel Bayer-sensor. But you could also say that now that we’ve ditched the AA-filter and circumvented the mosaicing, we are – finally – getting the full resolution of the sensor, in the case of the A7R III: 42 megapixels…

Hugh Brownstone says the A7rIII is the best “medium format” camera of the year. It means it kills the reasons why people usually bought Medium Format cameras:

Jim Kasson says the Sony a7RIII still eats stars

Jim Kasson analyzed the A7rIII spatial filtering and found out that is “behaves” the same way it does on the A7rII. So his conclusion is that the A7rIII also eat stars. This statement goes against the findings from Drew Geraci who said last week:

“Very Excited to share this side by side comparison of the A7RIII (full production model) shooting Astrophotography at 3.2″ and 10” at ISO 12,800 utilizing the Sony 16-35mm GM lens. As you can see in the side by side comparison, with ALL noise reduction turned off in the main menu, you can easily see that all stars are present and accounted for when blown up at 100% resolution. The star-eater is no more.

Password: star”

While Jim Kasson did yet not test this on real start shoots I really do trust Jim. And I worry that at the end he might be right. Unless Sony did something on the A7rIII we don’t know about. I hope further testings can confirm if the A7rIII will or will not eat stars.

New Sony A7rIII tests and videos

Albert Dros shared his “First Day” findings with the new Sony A7RIII:

The camera feels good, lot of faster than its predecessor.
Sound of the shutter is different. Sounds a bit ‘smoother’, like there is less vibration going on.
The resolution of the viewfinder and the screen are better. This is really noticeable if you’re used to the A7RII.
Touch-focus is great
Focus-magnify during AF is great, works well together with the Touch-focus.
Custom menu makes me work faster not having to go through dozens of menu pages.
The eye-piece sensor is better.

Sony 24-105mm review by Marc Alhadeff: “Sony has delivered a superb lens, much better than the 24-70mm Zeiss”


Sony 24-105mm at Amazon, Bhphoto, Adorama, BuyDig, FocusCamera, Amazon DE, Calumet DE, Wex UK.

Marc Alhadeff posted the detailed review of the new 24-105mm lens. I did actually preorder this lens before to read any review and I was worried that once first reviewes would be released I might would be disappointed. But luckely this doens’t seem to be the case:

The Sony 24-105 F4 was longly awaited by Sony users as a key trans-standard zoom

Sony has delivered a superb lens , much better than the Sony FE 24-70mm F4 Zeiss OSS, way above the Sony FE 24-240mm F3.5-F6.3

  • The lens is always excellent in the center and corners are just 1 grade below but can always reach the very good grade
  • Bokeh is very nice, with beautiful blurry background
  • Very good resistance to flare, no CA
  • Very nice results in video with nice blurry background
  • Construction is very good  and lens is equipped with all relevant knobs : button than can be assigned to eye AF, AF/MF switch, Optical stabilisation

The tradeoff made to sacrifice distorsion (quite important) for sharpness is a good one to my opinion as those will be automatically corrected by a lightroom lens profile very soon

With its correct price tag of 1350 euros, I expect this lens to become the standard high quality zoom lens for A7RIII/A9 if you don’t want to invest in the Sony FE 24-70mm F2.8 GM

Highly recommended !

This is how weird moving objects look in Sony A7rIII Pixel Shift mode

Darren Soh from our Sony A7rIII FB group (join here) shared some more findings on the A7rIII Pixel Shift Mode (Click on images to enlarge). First let’s see that image of a jogger in the Park:

Darren writes: “100% crop comparison of one shot (left) and pixel-shifted image (right). A glitch in the matrix occurs when any changes happens between the four exposures – here, a jogger is running by. Even his shadow is recorded as a glitch.

Of course this was expected. It’s nearly impossible to avoid such artifacts on moving objects. Maybe some future algorithm could make it possible to remove moving objects from the frame. But for now you have to deal with these kind of issues when you don’t shoot absolutely static objects.

That said the new Pixel Shift model really delivers superb results. Darren writes:

(image on top) 100% crop comparison of one shot (left) and pixel-shifted image (right). Notice the elimination of moire in the staircase grille.
(image below) 100% crop comparison of one shot (left) and pixel-shifted image (right). The gain in microcontrast is astounding.
