The D-BG2 battery grip is for exclusive use with the PENTAX K10D or K20D. This battery grip can be used in combination with the camera's rechargeable lithium-ion batteries to double the camera's battery life. With a vertical shutter-release button, preview lever, two control dials, AE-lock button and green button, the new battery grip makes vertical-position shooting simple and effortless. It also features the same dust-proof, weather-resistant construction as the K10D camera body.
