The Olympus HLD-6G is a handgrip for the Olympus OM-D E-M5. By itself, it gives the camera a more positive grip and repositions the shutter release, which is nice for larger-handed folks. The HLD-6P is a battery holder which attaches to the bottom of the 6G and provides a vertical shutter release and a pair of function buttons, plus room for a second BLN-1 battery (included). In excellent condition, with all rubber caps.
