Developed for exclusive use with the PENTAX K10D & new K20D, this battery grip can be used in combination with the D-li50 lithium-ion batteries to greatly extend the battery life of the camera. With an extra shutter-release button, preview lever, electronic dial, AE-lock button and green button, it makes vertical-position shooting simple and effortless.
The battery compartment provides storage space for a memory card and remote control next to the batteries. It also features the same dust-proof, water-resistant construction as the K10D camera body.
