Pentax K-m Prime Lenses

"I have been very satisfied: this lens is absolutely great for low light, or portraiture, requiring large apertures. I shoot with a Pentax k-x, non full-frame, and so the focal length is closer to 85 mm, perfect for portraits."

"Stellar performer. Very sharp, and works well with in-body stabilisation, which is more noticable/effective at this focal length. Suprisingly good bokeh! This has now become my default lens bushwalking, with a shorter macro and wide prime in the bag. Very versatile thanks to close minimum focus distance. Not as big as imagined. About as heavy as expected (not light, but probably good for this class of lens). Overall GREAT and well worth the investment."
