Such a shame that Zeiss doesn\'t do AF on the Canon mounts. Impressive IQ nonetheless.
there are no AF sensitive enough to handle F 1,4 and critical works and its there at 1,4 Otus rely shines.
I have no problem getting consistently in-focus 50mm shots @ f/1.4 on both my Canon and Nikon bodies.
well , the AF sensitivity is F 2,8 (in reality 3,4 in some cameras) and if you not use live view and go by the AF assistance with Otus you have a minor variation of the sharpness plane in the depth of F 2,8
take 5 shots and use the AF assistance and go from infinity to the target distance 2m and do so for every shot and I promise you that you get different plane of sharpness in your shots at 1,4
And if you use a high resolution camera as d800 you se it more clearly
OR do a test with your AF 1,4 lens at 1,4 , take 5 pictures and let the camera re focus between the shots, put your hand in front of the lens or go to infinity and then let the AF focus, you have a serie of different focus plane at 1,4
