When the lens is to be used for close-focusing, the Leica Macro Adapter M is attached to the camera body instead of the lens. The lens is then mounted on the adapter after rotating it 180°, i.e. with its lower side turned up. In this position, a second pair of distance and depth of field scales for the respective focusing range becomes visible, enabling easy reading from above.
The adapter also features close-up correction for the rangefinder focusing system. Comes with a leather belt case, with belt loop.
