I'm very happy with the FA 28-105, although I have very little experience with autofocus zooms. It's become my favorite walkaround lens with the *ist-D. The range is near perfect for most of what I shoot on a just-for-fun photo walk. I can't fault the sharpeness, although I rarely use it wide open. I've made 12 x18 prints that are very sharp to my eye from exposures made at f8. Sometimes I combine it with a 17-35 Sigma if I want more coverage at the wide end.

Comments on Stan's Pentax site are limited on this lens, I'd like to know more about it.
I'm enjoying the mixture of F series modest-aperture zooms and faster A series primes. :-)
