Quote:You can't compare SLR lenses with lenses for mirrorless anyway... Lens design is different due to different distance to the film plane.

And then there is the difference between FF and APS-C needed image circle to consider also.

That Mitakon 50mm f0.95 shows to be too narrow too, with quite heavy cats eye-ing expect in the center of the frame.

Ah, so in this case it's the flange distance that makes or breaks the design. Makes sense. Thanks.
