Clearly not! OK, let me put the question another way - is there any reason why these lenses shouldn't perform equally well on the Nex7, for example, because of the distance from rear element/lens flange to sensor plane?
these lenses are all retrofocus design which should theoretically work well on the NEX 7 which does not appear to be tolerant of extreme ray angles of older rangefinder lens design - i would bet they're superior to any of the existing e-mount lenses
