The Pentax K-m (called K2000 in U.S.) is a 10.2 megapixel digital single-lens reflex camera, announced on September 22, 2008 at the 2008 Photokina trade show along with the DA-L series of lightweight, inexpensive lenses.The K-m is considered a compact and entry-level model. It is significantly lighter than other Pentax DSLRs, lacks the weather sealing of the contemporaneous K200D and K20D models, and is intended to be sold with lightweight DA-L-series lenses. It does offer some improvements over the K200D, however, notably a maximum sensitivity increased from ISO 1600 to ISO 3200 and a slightly faster burst mode.
