BTW, have you tried comparing its results on film to what you see
with the digital camera?

I would be very interested to hear about PDML members' experiences
with the 15/3.5 on a DSLR. Several months ago I bought a used
A15/3,5 primarily for use on film, and I've been very disappointed
with its performance on my *ist-D. Compared to the DA14/2.8, my
A15/3.5 has poor sharpness and contrast, particularly at the edges.
even when stopped down to f8 or so. I sent it to Pentax USA for
service, thinking that it might be poorly collimated, but repeat
tests after it came back still show it to be rather poor on my D.
Perhaps this is one of those lenses which just don't perform well
with digital sensors, despite acceptable performance on film. Or
perhaps I just got a bad copy...
