Pentax 40mm Pancake lens SMCP-DA f/2.8

Small & compact I can put my K-01 in a coat pocket. Give very good pictures with both my K-01 & KP. Even very good at f/2.8, inaddition to beeing very sharp the colors are very good. Can be used to near macro distances. The lens is so thin that it is hard to get enough grip at the body flange to moiunt & unmount the lens. If not mounted all the way it will not auto focus or adjust apertue.

Little known gem covering full frame

This lens likely holds the record for the best image quality per dollar and gram. The less known fact is it actually covers a full frame circle. Resolution is excellent even at f/2.8 and drops only to the very far corners for less than 1% of the full frame. Colors "pop out" in classic Pentax glass tradition and bokeh is beautiful. For the weight and size it should never be off the camera bag.

Great lightweight and/or "stealth" lens

Bought this for using on a K-5 while engaging in dual sport motorcycle riding. Will be a good compact light-weight way to capture scenic photos. Anticipate it will also allow unobtrusive candid street shots.
