DPReview updated their studio scene with results form the Sony a7RIII and personally, I find the high ISO results less than impressive. I always like to go straight to the more fibrous/3d parts of DPReview’s studio comparison when looking at how a camera performs and while base ISO looks pretty good I wouldn’t use the a7RIII above 6400 ISO. By 12,800 ISO the a7RIII loses too much detail, but there might be a slight issue with DPReviews test if you pixel peep around. At times the a7RII looks better than the a7RIII, while the D850 and GFX almost always look a little better. Maybe the small Sony a7 is a little off axis during testing or maybe this is an optical weakness.
Some sites might try to paint a rosy picture here, but the a7RIII does seem to be performing below the a7RII in some respects and it is very hard to tell if the testing is flawed or the camera. Thankfully the performance claims of the a7RIII do seem to live up to expectation from the videos that we have seen on Youtube, but the a7RIII won’t be replacing the a7S anytime soon.
