Lenses that have a Pentax SDM focus motor

"I've used this lens now for about 1200 shots of lacrosse games taken in the evening/night under the lights, bright sun and cloudy days. Great resolution when the focus is spot on." bhphotovideo.com

"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." bhphotovideo.com
