leping,
thanks for the clarification, yes my 45-85mm FA is not bad at 45mm at f11, F13.
just started testing my 35mm FA.

Your welcome. A useful 67 lens ration, on film, can be found here (as I posted several times -- ratings in this database agrees 100% with my experiences with the 67 lenses I owned -- again, on film):

Pentax 67 Lens Guide

Notice the 45mm was not a bad lens on 56x69mm film at all, even with the little CA issue. However now we found it is only sharp over the center region on a 33x44mm digital sensor... Quite a different animal.
