If you could give me an example, We can try to accomodate it given the
lens options that we have available to our test. There are several *
lenses in our lineup, and other non-* legendary lenses as well. I.e. I
don't know if there is a difference between the A* 300 2.8 and the FA*
300 2.8, but we will find out. They have different optical formulas.
If you know the answer to some of these differences on film, by all
means share. We will probably not do a film test, it just adds another
dimension we are not prepared to undertake right now.

Ok, thanks for the feedback. Have you specifically
found ANY pair of OUTSTANDING lenses that you could see a difference
between the two on fine grain BW film but the istD was unable to resolve
the that difference? I say this because I am specifically concerned
about its ability to resolve the differences between the finest
lenses out there, not just see differences between excellent, good, and fair
lenses...

So now I will ask a question, is the resolution of the istD
series cameras high enough to tell the difference between an
excellent and a slightly better truly exception lens In the APS region it
covers? Or does at some point the resolution become "camera limited"
and two lenses both outstanding but slightly different
performance become "one" and these differences are not
resolved at all as they clearly would be on film grained BW film?

Oh you can tell the difference instantly. I've compared several lenses
in the same focal range but different levels of quality and the results
speak for themselves. I'm about to undertake a more substantial project
with another PDML member to document lens characteristics of various lenses.
