The Pentax 55mm f/1.4 DA* SDM Autofocus Lens is a compact and bright short-telephoto lens of the highest order, made exclusively for Pentax digital SLR cameras. In a stocky housing ready for harsh conditions, you'll get a bright f/1.4 aperture-worlds away from the experience you're used to with more common zooms-that opens up new creative doors to you as a photographer. This lens was born to shoot between f/1.4 and f/2.8, and comes with a 9-bladed aperture diaphragm which shows up as perfectly round when you stay between f/1.4-2.8.
