No, they don't. They look like the pictures I took with my A15/3.5 on the *ist D. Pictures I took on film (usually shot on color slides such as the Sensia 100) with the same lens were far better. On film, all apertures f/5.6 to f/11 are more than useable, while I tried to avoid shooting at f/3.5, f/4, f/16 and f/22 because of noticeably lesser sharpness. I don't know which is the weak ring in your chain, but the 15/3.5 can deliver better sharpness for sure. I've been told the 15mm (all 15mm lenses, not the Pentax) to be very critical about alignment of optical elements. Can this be the possible reason for its poor performance? Dario Bonazza
