Better Grip, Better Shots. The Leica HG-DC1 Wireless Charging Handgrip attaches to your Q3 via a 1/4 20" mount, and allows the camera to fit more comfortably in your hands. This all metal unit enables a wireless charge to a BP-SCL6 battery when used with a Qi-enabled charging mat, like the Leica Drop XL Wireless Charger. On the side of this handgrip you’ll find another mounting point that you can accessorize with optional finger loops, too.
