Perfectly matched to the Leica Macro-Elmar-M 90 mm f/4

The adapter is designed to be mounted between the camera and the Leica Macro-Elmar-M 90 mm f/4. Its integrated helical screw system allows a variable extension of the lens of between 18 and 30 mm and thus enables the variation of the reproduction ratio. When mounted on the adapter, the Leica Macro-Elmar-M 90 mm f/4 can also be used in its collapsed position for exposures up to infinity. Thanks to a new locking function, this allows photographers to set any distance from 41 cm (reproduction ratio 1:2) to infinity without having to dismount the adapter.
