Originally posted by Smolk Yes indeed, these comments only apply to film, on the 645N, not to the 645D. I cannot comment on the D. But I thought it was fair to point out that the A and FA are not identical and so I dug up a quote from my database.
They may well perform differently, since the 35A and FA do that on the D as well, apparently. That's why I wondered whether DigiLloyd had anything to say on the FA version vs the A of the 200mm.
Hi Smolk: Digiloyd did not test the 150A fully, but he did a side by side comparison test of the 150A and the 80-160 FA at the 150mm setting. His findings on the 645D are quoted below:
Conclusions
The 80-160 is visibly inferior to the 150mm f/3.5 prime lens. I would not consider it worth using on the Pentax 645D, at least not at the 150mm mark as tested here. However, it performs much better at the
80mm and
120mm settings.
