Dedicated to the Leica Q3, this Thumb Support offers a more stable and steady grip while using the camera. This support attaches to the camera via its hot shoe and provides an ergonomic thumb rest for increased comfort and a more secure hold, especially when shooting one-handed, and it has built-in pass-through buttons to retain control over the function buttons on the back of the camera. This Thumb Support is made out of aluminum and has a silver anodized finish.
