Leica Elmarit-R 28mm f/2.8

A wide-angle prime produced in two versions for the Leica R mount, starting in 1970. The first version used an 8-element-in-8-groups design with a close focus of 30cm, while the second version, introduced in 1994, added a floating element for improved close-range performance. Roughly 50,500 units were made, including a small run in Safari green.
