Sliding the thumb rest into the accessory shoe enhances the ergonomics of the Leica Q2. With the thumb pressed up against the thumb rest, the camera can be held much more steadily and is easier to handle. It makes single-handed shooting much steadier and enables the use of longer shutter speeds without the risk of camera shake. The integrated button allows continuing operation of the thumb switch. The coating and the lettering on the thumb rest are perfectly matched to the Leica Q2 and guarantee perfect visual unity.
