The Handgrip M from Leica is the basic
handgrip for the Leica M Digital Rangefinder. It attaches to the
camera's base plate and provides a stable grip for the right hand while
shooting. It is particularly useful when shooting one-handed or while
using heavier lenses in order to maintain stability. A textured black
rubber surface provides a sure grip and a screw mount is available for
the optional finger loops that can be attached for further control.
