280mm · f/4
The Leica APO-Telyt-R 280mm f/4 is a cult lens praised for exceptional sharpness and color accuracy, with apochromatic design minimizing chromatic aberration. It shows modest vignetting wide open, negligible by f/5.6, and low distortion. Build quality is superb with smooth focus and aperture, though the tripod foot lacks a standard quick-release plate. Its lighter weight makes it easier to handle than f/2.8 counterparts. Suits photographers needing high resolution on high-MP cameras, especially with EVF adapters on Leica M or mirrorless systems.
