So as a battery handle for a K3 more than useful! If you're not exactly small petite woman hands! Because with normal hand size is always the little finger to the ring finger also bore without stopping! Especially since it is very convenient if you make time portrait the shutter at the right place without having to contort his hand! The battery grip is yes driekt by the manufacturer, so that everything fits! If you already bought a camera of 1000 can also be the numbers! In practice this is one can accommodate an additional SD card! I would buy it again!
