The Leica 90mm f/4 Macro-Elmar-M for Leica M is a compact short-telephoto prime for Leica M-mount cameras. Key features include:

Short Telephoto Prime. The Leica 90mm f/4 Macro-Elmar-M is a retractable short-telephoto prime that boasts a 2.6-foot minimum focusing distance and 1:6.7 reproduction ratio, making it excellent for close-up photography. It’s compatible with the Macro-Adapter-M, which gives you a 1.4-foot minimum focusing distance, 1:2 reproduction ratio, and infinity focus on cameras with live view.

Advanced Optics. This lens’s four-group/four-element design gives you sharpness and illumination throughout the zoom range, while the anti-reflective coating minimizes flare and ghosting for contrasty, color-neutral shots.
