Thanks, all - this looks pretty definitive, and it's confirmed the conclusion I've (slowly) been coming to myself.
Originally posted by wstruth I read your post again and realized your were thinking of using DA lenses on the pending full frame.
Actually I was thinking in terms of what the release of the full-frame, and knowledge of how it works with crop lenses, will do to DA lens prices. So it's worth holding off at least to the Black Friday sales or until the FF is released/specs are fully known, or both.
Regards the full-frame itself, I'm almost certainly going to be a late adopter; my K-5 is kicking along nicely right now, and I see no urgent need to replace it or supplement it unless that state of affairs changes (*knocks on wood*).

While I'm thinking about it, how do these DC lenses perform on manual-focus bodies? I know that interface of my DA40 Ltd and DA50/1.8 with my P3 and P30T is strictly program-mode-only, but they WILL mount and fire and AFAIK they will do so with correct exposure (though I'll only know for sure when the next roll of film comes back!). Does anyone out there have a P3/30 series camera and an 18-135 they can slap on it and find out? (The P50 is a different, more sophisticated beast, and I'm not sure I'd care to extrapolate backwards.)
