I beleive the M, A and F 28 f2.8's all have the identical optical
formulas, (well there's an earl and late M version, which was
different). All were, at one time, considered mediocre performers
though If you're deciding between these three I'd get the F if I had
a choice, (better coatings and auto focus, next would be the A, (for the
A contacts, then the M. On the other hand the M lens most likely would
sell for 1/4 to 1/3 the price of the equivalent A lens..I don't think
I've ever seen a F for sale. I don't theink they made a whole lot of them.

How do the M and A 28's compare? Is there a really good one or (more
