I agree and disagree with this. I do love my DA lenses, but I also love my F and FA lenses. I can't really tell if my "nifty fifty" is optimized for film of not, its tack sharp, and has excellent contrast and bokeh. Technically, I would easily say that my FA50 1.7 is better in some ways (many ways) than either of my DA limiteds. My FA100 2.8 macro is pretty awesome, and outside of quick shift and WR, I can't see any reason that the DFA 100 is better. The F35-70 is a strange beast, but its hard to find any optical faults with it (outside of its often bizarre bokeh) when shooting on my digital K-5 or IR converted K-x.
Further, the film lenses have a major up on the DA lenses... Aperture rings. A DA50 1.8 would be almost useless to me, since I couldn't reverse it, or use bellows, or tubes. Or use it on my micro four thirds system. Or use it on the mythical Pentax FF camera in the future.
