I agree that people take Ned Bunnell's statements a little bit too far. I think his argument should be more read in the spirit of "Well, we know our lenses -- some old, some new and designed for crop sensor format -- already work well on Camera A, but they might not do so well on more demanding full frame Camera B, and some of them won't work well at all. Therefore, isn't Camera A the smarter choice?"
And until Pentax/Hoya commits to coming out with new FF lenses, it's sort of hard to disagree with him on this point. Although personally I would love it if Pentax bought the Nikon D700 sensor, shoved it in the K-7 body, and let people try all their legacy glass out on it. But that, among many reasons, is why I am not in charge of an international camera company
For discussion purposes, here's an oldy but goodie thread from a German discussion forum where someone converted their FA31 to work on the 5D Mark II:
DigitalFotoNetz.de :: Thema anzeigen - Pentax FA 1,8/31 an Canon 5D II
Looks like pretty decent results for a mount and camera it wasn't designed to work with.
Also, here's the FA31 on a Canon 5d (not as much resolution, i know)
???: ???? Pentax FA 31 LE & Canon EOS 5D
He also converted the FA43:
???: ???? Pentax FA 43/1.9 Limited
And the FA77:
???: ???? Pentax FA 77/1.8 Limited
Can someone with more technical knowledge than me explain why these lenses would work on these Canon FF cameras but not on a Pentax version? Assuming, of course, that legacy glass will be accepted on a full frame Pentax camera should it ever materialize.
This camera might not be as kind to lens flaws as an APS-C sensor camera would be (the edge softness of the FA*24 f/2 wide open might be worse on FF for example) but the lenses would still *work* would they not?
