After benchmarking in controlled conditions at 1/400th, f/1.4 + f/2 and 800 ISO I may have to retract some statements.
I didn't lock the exposure, you can see my settings on the camera. If anyone would want to suggest a different benchmark I can do that later. I don't own a light meter though so I cant provide that info right now. I should probably buy one.
Also looking at these together its clear the radioactive yellowing of the lens is still there even after a few days of blasting it away, for the Concave Canon FD 35mm f2 MF
