The Pentax K10D is a K mount APS-C format camera with a 10mp CCD sensor and some light weatherproofing: a stalwart camera from the first few years of Actually Good DSLRs (2006). You're not getting high ISO performance with this camera- it tops out at 1600, and things are kinda dicey up there- but you do get an in-body stabilizer, which is pretty forward-thinking. The K10D is compatible with almost every Pentax K mount lens, manual or autofocus. No video functionality or live view at all on this one, though: it's strictly stills. In excellent condition, with only light wear. Includes battery and charger.
