Pentax K100D &nbsptype_Digital Camera adjusting shutter speed while youThe 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. This one has just under 20k actuations and is in excellent cosmetic condition, with only minor wear.
