My huge question is about the phase autofocus of the m1. It should theoretically make a c-autofocus just like on SLRs, so it can track focus as you move, as opposed to contrast autofocus.
A freind of mine uses a nikon full-frame, and is tired of the size and weigth when bringing it somewhere. He is considering the m5-II. But when he tried my m5 with the 60mm in c-af mode, he found that c-af is (as I told him) totally useless. Of course the m5-II is faster, but it still uses the same focus principle. It will continuously go in and out of focus as you change your distance to the subject slighty. Does the m1 indeed track focus in c-af like SLRs? In that case it should be a big advantage compared to the m5-II.
