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 longer, it enables macro photography up to a reproduction ratio of 1:2 and, with wide-angle lenses, even larger ratios. Adjusting the distance between lens-to-sensor is easy to do by rotating the knurled ring.
