Summary: Though it looks strange on my Pentax K100D I really like this lens. Its sharp across the field when stopped down a couple of stops but still usable wide open. I also bought a Tiffen 28mm UV filter with it in order to protect the lens.
Summary: Very slim. Focusing seems to make a bit more noise than with some other lenses, probably because the camera uses its own motor. All Pentax lenses are overpriced nowadays, but this one was a relatively good deal.
Summary: My second prime lens.It works beautifully!!! My first pancake lens as well. I am a Pentaxion from way back,and my 2 Pentax dSLR's are getting lots of lenses,mostly Pentax. I have to learn all that this lens can do,and I am enjoying practicing!!
Summary: I took over 2000 pictures w/o flash on my k7 at museums in paris over three days. Did not really use up my pair of batterys doing this. I used full auto mode, and found the auto focus speed very fast.
Summary: This is an AMAZING bargain. Good: Small light fits in small bags fast focusing metal mount One of the least expensive Pentax lenses low distortion At 61mm (on a Pentax body) it is good for indoors as well as outdoors.
