The A7r was overexposed by at least 1.5 stops, probably even more. Look at the yellow walls, pushed into pure blown white on the -R but close to 2 Ev down on the A7. User errors should not be blamed on lens/camera.
I do see a larger shift towards the absolute corner though, but you\'d do best to ignore the rest of the image.
I see that the link I posted stopped working, I think this will:
So not only is the color difference emphasized, there seems to be some odd arc in the A7r photos -- do you see what I mean? It should be pretty obvious. I find it very curious!
I have seen that posterized effect in a few A7r + adapted wide rangefinder shots, particularly when pushed to extremes as here. With extreme processing, that effect has also shown up with other Sony lossy raw images and I have wondered if it\'s at least partially due to the lossy compression going on. There is a lot of data being thrown out with the Sony lossy raws (non lossy sony raws from 24MP\'s are the same size as the current lossy 36MP raws for instance). Sony claims it\'s not visible but perhaps in extreme processing, it shows up where it might not with non lossy raws.
