Hi All, I suspect this question had been discussed before, but I was not able to find direct comparison of these lenses, (except for this response from Margus Mannik http://www.mail-archive.com/[email protected]/msg231174.html no practical responses to a similar question from Joseph Tainter, and comparison of D-FA with F (not FA) on a German website http://forum.digitalfotonetz.de/viewtopic.php?t=12835 )
Pentax SMC (AF): FA 100/2.8 D FA 100/2.8 FA 135/2.8 F 135/2.8 Any comments on comparative optical (and otherwise) quality of them? Any difference in AF speed and accuracy? Do D-FA and FA 100 have the front element rotating? Does anybody know what type of issues (if any) of FA 100/2.8 with *istD(s) (per Bruce Dayton: http://www.mail-archive.com/[email protected]/msg225279.html )? What would be reasonable prices that one can find for any of these lenses used, in good condition? Thank you, Igor
