reviewswhat are people saying

"It is capable of stunning color and sharply isolated portraits with a very neat bokeh. I have 2 K100d bodies, a K20, and a K-x, and unlike my other lenses, it does equally good on all four of them! The bright f/2.8 ratio makes this a winner indoors and also outside for depth of field control."

"I use this lens semi-professional and I am extremely happy with this price/quality combination. Constant 2.8 output across the whole zoom range, outstanding resolution and warm color rendition make this lens one of the best choices for Pentax users."

"Plastic housing feels cheap, but no problems so far. The soft plastic lens hood is hard to put on and take off, par for the price."
