The Leica Macro-Elmar-M 90mm f/4 Lens is a prime telephoto lens featuring a retractable design to maintain a compact, portable form factor. The 90mm focal length and manual focus design is well-suited to portraiture applications, as well as for reportage from greater distances. 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.
The simple lens design incorporates four elements within four groups and each element has been coated with a multi-layered anti-reflective coating to reduce lens flare and ghosting for color 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.
