Origins

Leidolf and Leica being two of the oldest camera manufacturers, only having one battery grip available compared to the hundreds of battery grips made for the other camera companies.

Good Uses

Vertical grip; the battery grips gives the camera a more square shape that no matter what side the camera is turned, there is enough grip to hold it vertically.

Easier to hold smaller cameras for people with bigger hands Some cameras are small that photographers who have larger hands have a harder time holding the camera. The grip gives the camera more surface area for the photographer to hold onto.

Another shutter release button when held portrait; when turned vertically the, depending on the battery grip their is a shutter release button so that it mimics the shutter release button when holding the camera horizontally.
