Sony Alpha 7R II Review – Image Quality: Dynamic Range

Dynamic Range

At the Alpha 7R II’s lowest native sensitivity, our dynamic range figures measured 13.1EV at ISO 100. This sensational readout puts it ahead of the Sony Alpha 7R, which measured 12.4EV at the same sensitivity. Results remain above 12EV right up to ISO 800, indicating there should be plenty of additional shadow detail retrievable from raw files. Beyond ISO 800, results drop slightly to 11.5EV at ISO 1,600 and 10.2EV at ISO 3,200. Pushing up to ISO 6,400 sees the dynamic range drop to 8.5EV, indicating that detail in dark areas of an image is increasingly lost to noise. As the chart above illustrates, figures remain above the critical 6EV right up to ISO 51,200, only dropping below at ISO 102,400.

    I’d just like to address a couple of points to the reviewer:

    1) With the A7R II having a 7952 x 5304 pixel sensor array, doesn’t it mean that – at a pixel density of 300ppi – you would be able to print up to a maximum of 26″ x 17″, without resampling, and not 22″ x 15″?

    2) The camera’s LCD/TFT monitor is ‘the same’ only in the sense that it shares the same 3″/7.5cm diagonal dimensions as the original A7R. For the A7R II, Sony has i) altered the tilt angles of the assembly (it can now tilt up 107 degrees and down 41 degrees, as opposed to up 90 degrees and down 45 degrees for the original A7R), and ii) the display resolution has increased from 921.600 dots (A7R) to 1.23 million dots (A7R II)

    If you want to try astrophotography, surely you would be better off with a Nikon D810A, or if on a lower budget, a Canon 60DA. Both are specifically designed for astrophotography, but will also produce excellent results with “normal” subjects. If you prefer the quirky design of Sony cameras, I’d suggest the A7S which is designed for low-light photography. It has “only” 12 megapixels, but that is more than good enough for a razor sharp A4 print.

    Sony are trying VERY hard, and it’s great to see a company being so brave and innovative, which creates competition and can only result in better cameras from other makers.

    Sony cameras have fantastic specifications, and sensors that are way ahead of the competition, but there is more to a camera than specification. It is also vital to have a complete lens range (Sony have a rapidly expanding lens range but it still can’t match what is produced by Nikon or Canon), and camera bodies that handle well and will survive knocks and showers.

    Unfortunately this is the area where Sony continue to fail. The A7iiR has better control layout than previous models, but is simply not in the same league as Nikon and Canon. Sure, it’s possible to adapt to the quirky design, but Sony definitely needs to pay more attention to ergonomics if it really hopes to challenge Canon and Nikon.

    Someone on another website stated that Canon and Nikon produce cameras, but that Sony produce gadgets, and unfortunately that is exactly the impression that the A7 series conveys. Wonderful little machines and fun to play with, but not for professionals who are looking for a tool not a toy.

    Awesome, thanks!

    Without running a direct head-to-head with both cameras and analysing a series of the same images side by side it’s difficult to draw a comparison. However, that said the noise performance on the Alpha 7R II is exceptional and having thoroughly tested it through its sensitivity range and analysed my results in detail, I wouldn’t hesitate to push to ISO 6400 in low light. Usually I’m not too keen on pushing beyond ISO 3200 on my EOS 5D Mark III. When we can get our hands on another review sample we’ll try and post a low-light comparison to show how the Alpha 7R II compares to other current full-frame models.

    How would you expect the alpha 7R II to perform shooting night scenes vs. the Canon 5D Mark III, for example? Does the back illuminated sensor help to mitigate the high pixel count? Although it wouldn’t be my primary purpose, I am an amateur interesting in trying out some astrophotography. Thanks!
