Photons to Photos: Sony a7III Final Results and They Are Somewhat Shocking



I am not a big fan of some of the other sponsored sites out there because many of them get big money to promote cameras and even though I run sites with addict in the title I do not play with the numbers to make companies happy and I give my honest opinion on cameras. That being said I believe that Photons to Photos is the single best source for non-bias no bs sensor measurements on the web outside of maybe The Last Word run by Jim Kasson, but he doesn’t keep a comparative database.

Now that you know where Photons to Photos stands I am kind of shocked that the a7III seems to be slightly ahead of the a7RIII throughout much of the ISO range. Maybe Sony should have put a new sensor in the Sony a7RIII, because I am sure some owners will not be happy with the Sony a7III performing slightly above the a7RIII. The read noise win for the a7III isn’t surprising and it probably played a factor in the cameras great dynamic range performance throughout the ISO range, but still the Sony a7RIII seems to only have a resolution advantage now and a few better features like the higher resolution viewfinder. You can manipulate the dynamic range results here and the read noise results here.
