DxOmark posted the full Sony A7rIII sensor test results. The camera matches the Nikon D850 score and leads the Full Frame camera ranking. DxO writes:

It’s clear that the Sony A7R III has a high-performing sensor that’s capable of capturing images with a broad range of color and tone, while keeping noise well under control.

However, comparing the A7R III sensor to the Nikon D850’s reveals the advantage that the Nikon camera’s lower minimum sensitivity (ISO) value brings. Photographers who predominantly shoot in bright light or capture motionless subjects with the camera on a tripod will record the most information, be it color, tone, or detail with the Nikon D850 set to ISO 32. However, if they require values above that, the Sony A7R III sensor produces marginally better images.

Sony’s in-body 5-axis image stabilization system is widely respected, and if it achieves the 5.5 EV shutter speed compensation in the A7R III that the company claims, it would enable the camera to capture images at ISO 100 instead of at ISO 3200 (provided the subject is stationary).

It’s impressive to see that Sony A7rIII matched the D850 despite two disadvantages: The Sony has no ISO 32 option and four less Megapixels. It would be nice if Sony could add lower ISO settings via firmware upgrade. But maybe I am asking the nearly impossible as it’s likely you need hardware to support this too?

Still to be honest we would rarely use ISO 32 in real life shooting. And from ISO 100 towards the A7rIII beats the Nikon on all charts:

Impressive!

Dpreview noticed that the new A7rIII is indeed “eating” fewer stars than the previous A7rII:

The Mark III does show an improvement: there are stars that aren’t there in the Mark II shot, and there’s generally more ‘pop’ to the stars. This is encouraging, but it’s also difficult to rule out how the spatial filtering algorithm interacts with shots that might be ever-so-slightly focused differently.

For more technical insights on this jump over to Jim Kasson‘s blog.

What Sony should do is easy: Add an option within the menu to disable spatial filtering when shooting stars. That said normal night sky shooters like me and 99% of the readers will not have any issue with Sony’s normal setting. This because only a limited amount of very small stars (1 pixel size on the sensor) will get cut by the filter.

This is a guest post from Dylan Giannakopoulos. Original article at dylangiannaphotography.com.au

David Vogt and Hanna Saba both tried to answer this simple question in their video reviews:

Rokinon/Samyang 35mm f/1.4 at BHphoto, Adorama. Amazon. Amazon DE, Amazon UK.

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 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.

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:
