Grip D-BG2 - Overview
Designed for the PENTAX K10D and K20D cameras. The battery grip D-BG2 is powered by PENTAX rechargeable lithium-ion D-LI50 battery. Since it supplements the camera's battery as an additional power source, the number of recordable images is greatly increased. To facilitate vertical-position shooting, this grip features extra shutter-release button, preview lever, electronic dials, AE-lock button, Green button and AF button. It also provides the same dustproof, weather- and cold-resistant construction as the camera body itself. Part number: 39557.
