Well, Butch, it is difficult to say exactly what the changes in SMC treatments were, since Pentax has never really provided details on SMC treatments. Of course, Pentax has been changing SMC details for decades now, and generally the changes are assumed to be for the better. In the case of the M-to-A differences, some of the A lenses might provide a slightly warmer color than their M counterparts (or maybe it was that the M lenses were a little cooler. It also appears as if there may have been a slight improvement in contrast, M-to-A. However, the sizes of these sort of differences are probably fairly small.
