APO-Macro-Elmarit-R 100mm f/2.8
Iconic LensKnown as "R 100 APO", "King of Resolution"
The optical resolution benchmark of the entire Leica R reflex system.
Engineered by optical mastermind Lothar Kölsch and unveiled in 1987, the APO-Macro-Elmarit-R 100mm f/2.8 achieved unprecedented MTF chart performance across the entire focusing range from infinity down to 1:2 reproduction (and 1:1 with the Elpro). Its true apochromatic correction eliminates color fringing entirely, making it a legendary reference optic for medical, scientific, landscape, and macro reproduction.
