The Leica M10 Thumb Support in Black enhances the ergonomics of the M10 by slotting into the hot shoe. With the thumb pressed up against the thumb rest, the user is able to hold the camera much more steadily and it is then easier to handle. It makes shooting with one hand much steadier and allows the use of longer shutter speeds with less risk of camera shake. Machined from brass and finished in the same coating as the M10 to ensure a perfect match. Also available in silver to match the silver chrome M10.
