Quote:I wouldn't be so quick to dismiss imatest. Even Optikos' MTF bench has software that goes awry every 20-30 minutes, yet it gives some of if not the best MTF measurements you can get. And it's about $250,000-$300,000 =)I am not talking about this specific test, in the past there have been results on PZ with much too low imatest CA "measurements" (I do not know the reason for why the test shows that, obviously. Perhaps it can be focus distance related?), where the images show way worse CA performance.
1-2px max in the edge of the frame is pretty consistent with the sample images.
