Cet adaptateur est fait pour la photographie rapprochée. Il augmente le tirage et permet une distance de mise au point comprise entre 0,77 et 0,55 m avec un rapport de 1:3. Il se monte sur la baïonnette du boîtier, exactement comme avec un objectif.  Sa conception garantit une correction automatique de la parallaxe et une position correcte du cadre du viseur.

As the Macro-Adapter-M is also compatible with other M lenses, it offers Leica M photographers an even wider range of opportunities for creative composition and additional variety in reportage portfolios. With Leica lenses from 50 mm and greater, it enables macro exposures up to a reproduction ratio of 1:2 and, with wide-angle lenses, even larger ratios. The lens-to-subject distance decreases with decreasing focal lengths. The use of the adapter with 28, 35 or 50 mm lenses creates fascinating effects. The short distance from the subject creates extremely distorted perspectives and highly selective sharpness. Because, in contrast to a macro lens design, the imaging performance of these lenses is not optimised for such close focusing distances, it is advisable to stop them down by one or two aperture values. The use of the Macro-Adapter-M with lenses with focal lengths of less than 28 mm is not recommended, as the lens-to-subject distance must be extremely short to allow correct focusing.
