Excerpt: After reading the many glowing reviews on this lens, I bid on this one on e-Bay and won it. It's easily now the very best prime lens in my kit (others are the 50mm f/1.4 and the 15mm f/4 Limited). Inasmuch as Pentax APS-C cameras have a 1.5x crop factor, this lens equates to the old 35mm film standard of 50mm - in this case about 53mm equivalent. Hence it "sees" things much like human vision, with no distortion through elongation or compression in the picture.
Excerpt: This lens is one of my top 3 favorites, along with the DFA 100 mm Macro WR and DA 21 Limited. I use the 35 for macro shots of botanicals or inanimate objects and the 100 mm DFA for butterflies, birds and dragonflies where the 100 mm is more suitable. Between the two lenses, I have all my macro needs covered. The DA 35 also doubles as an excellent normal lens as well.
Pros: sharpness, build quality, compact, doubles as normal and macro.
Cons: autofocus when going end to end from macro to normal
Excerpt: 35mm is my favorite point of view, and i was a happy user of the 2.4 "plastic wonder". But i wanted to try the upper-class. I have been looking for several months for a good second-hand copy, and finally managed to get one.
Pros: Sharp is not the word to describe this lens ("brutal" may be better), macro abilities
Summary: I can't say enough about the sharpness of this lens in consonance with my Pentax K3! I have detail that I've just never seen before even with my 6 X 6 cm cameras. This lens is ALL beautifully machined aluminum and is just smooth to say the least. Pentax did not add a motor; it only uses the cameras screw drive. It hunts once in a while but all Macros do this. I'll gladly give up the SDM motor for the size benefit of this little jewel.
