Nice fat focus ring makes fine focus a breeze
Good contrast
Excellent color
Smooth as silk bokeh
Lightweight
49mm filter

Auto focus can be a crap shoot.
Focus lock switch is a bit too easy to set accidentally.

I've used this lens on a K200 and a K7 and am nothing but impressed with this lenses abilities.
Sharp corner to corner from F2.8 all the way to F32.
Diffraction? You'd have to do some serious pixel peeping to find it.
Macros are outstanding and it isn't a half bad portrait lens, A bit too sharp maybe.
Even works well as a short walk around telephoto.
