OM System HLD-10 Power Battery Holder for OM-1 Series

The HLD-10 bolts to the base of an OM-1 or OM-1 Mark II and adds a second BLX-1 plus a full set of duplicated controls for vertical shooting - shutter, front and rear dials, AF-ON and the joystick all where your hand already is when the camera is turned. For portrait and vertical sports work that removes the wrist contortion that costs you frames.

It is sealed to the same standard as the body: IP53 rated, dustproof and freezeproof to -10C, so adding it does not open a weakness in a weather-sealed kit. In-grip USB-C charging means you can top up the battery without removing it, which matters on a multi-day trip where the charger stayed at home.
