I have the 21 F3.4 SA for the M and the 21 SA F4 for the R. The M
version does have more vignetting but is sharper, no traditional
distortion and a more even transition at the edges. As I shoot in B&W
most of the time, I don't really have an appreciation for color
differences.
>From tests of the 19 and the 21 ASPH the newest glass will have more
distortion but have much less loss of sharpness into the corners at
the expense of smoothness that the less sharp predecessors had.
