The Pentax K100D is a K mount APS-C format camera with shutter speeds from 30s to 1/4000s. It has a 6 megapixel CCD sensor with a built in shake reduction system and, perhaps best of all, runs on 4 standard AA batteries. Compatible with nearly all Pentax K mount lenses, manual or autofocus; a standard Pentax-DA 18-55mm f3.5-5.6 AL lens is included. In excellent cosmetic condition, with only minor wear, under 3000 actuations.
