Sony A7rIII dynamic range test by Dpreview: Impressive results!

Share

Dpreview tested the Dynamic Range of the new Sony A7rIII

1) The Sony a7R III retains its dynamic range even in bursts. That’s a big deal for a Sony ILC

2) The Sony A7rIII nearly matched the D850 performance. At ISO 100, the a7R III dynamic range actually exceeds that of the D850, thanks to incredibly low read noise. That’s impressive for a camera constantly running its sensor in live view.

3) The A7rIII has nearly half-stop improvement over its predecessor

4) As for Sony’s marketing, it sounds like the claim of 15 EV is believable, but only technically if you consider how your images look when shrunk to 8MP files. To be fair, there’s some benefit to comparing dynamic range figures after resizing camera outputs to 8MP, since it’s a common basis for comparison that doesn’t penalize cameras for having higher resolution (and therefore smaller pixels).

This is a good Job from Sony. But if Sony engineers could find a way to add a “real” ISO 64 to beat the Nikon…that would be lead to an even more impressive result!
