On the other hand the M6 is smaller and more compact than the M7, which has a lot of appeal, and the lens are of similar quality.
It is a shame that Mamiya chose to go with a different lens mount on the M7 as interchangeability between the two cameras would have given a much greater range of flexibility.
My understanding is that the M7 went with the non-collapsable mount so that they could add the 43mm and that this precluded interchangeability between the two. I would kill to have a 6 w/ the 43mm.
