Exclusively designed for the PENTAX K-1, this optional battery grip accepts six AA-size batteries as well as the standard lithium-ion rechargeable battery. It provides an extra set of shutter-release, AE-lock, AF, ISO, exposure-compensation and green buttons, as well as a preview lever and dual electronic dials to facilitate vertical-position shooting. It features the same dustproof, weather-resistant construction as the K-1 body.
