Photodo MTF Scores for Pentax FF and MF Lenses

Maybe it's time to check and review the old figures, there are at least six months to go! ;-p

And, the Pentax lenses I own are marked in Bold, although not all of my FF/MF Pentax lenses were tested by the Photodo, e.g., my FA31 and 77 Limiteds! :-D

And how do I have to read this? Grade 5 means the most versatile? ... or otherwise??

Do you think the release of the Pentax FF will drive up resale prices of the highest rated legacy lenses?

It might be.

Confirms what I thought. Pentax-F is better than Pentax-FA! Except a few like FA-85, which I have! I disagree with Pentax-FA80-200f2.8 measurement. Bad copy?

I agree with the result of the FA645 45mm, the resolution of the lens is bad, despite mine is already MIJ.

FA80-200 F2.8 was tested and rated as not very good by Amateur Photographer (UK mag), and my personal experience was the same, yet fanboys rave about them, and the 28-70 2.8 was all most as bad, all Pentax macros are excellent, the 50mm's even more so, the 100 3.5 is a Cosina but when you consider the price you can't argue.

Pentax were not good at making zooms, but their primes are excellent.

The DA 50-135 zoom is vg optically. (You're talking about optics, not motors I assume)?
