Designed for exclusive use with the Pentax KP, this battery grip features a dustproof, weather-resistant structure, and provides an extra set of control buttons (shutter release, AF/AE lock, exposure compensation/Fx3, and green) plus a pair of electronic dials to facilitate vertical-position shooting. It comes with the Grip L for improved handling when a telephoto or large-aperture lens is mounted on the camera. In addition to the standard D-LI109 lithium-ion battery (not included), it can also be powered by the large-capacity D-LI90 lithium-ion battery (not included) (a dedicated battery tray is included).
