Leica Macro Adapter M for 90mm f/4 Macro Lens

The Leica Macro Adapter M was specifically developed as an accessory for the 90mm f/4 Macro lens. It allows close focusing with this lens from 2.5' (0.77 m) (reproduction ratio 1:6.7) down to 1.6' (0.5 m) (reproduction ratio 1:3).

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.
