The Leica Macro-Elmar-M 90mm f/4 Lens is a prime telephoto lens with a retractable design for portability. With a 90mm focal length and manual focus design it excels at portraiture, and in any situation where the ability to work from a greater distance is required. When working with close-up subject matter, the lens is able to achieve a minimum focusing distance of 2.6 with a reproduction ratio of 1:6.7. It incorporates four elements within four groups, and each element is coated with a multi-layered anti-reflective coating to reduce lens flare and ghosting for colour neutrality and increased clarity. When coupled with the optional Macro-Adapter-M and used on a camera featuring live view, this lens is also able to achieve a minimum focusing distance of 16.1" with a reproduction ratio of 1:2. The lens retractable design also enables it to maintain infinity focus when used with the Macro-Adapter-M.
