400mm · f/2.8
The Leica APO-Telyt-R 400 mm f/2.8 is a super-telephoto lens known for exceptional sharpness and contrast, with apochromatic correction minimizing chromatic aberration. Its fast f/2.8 aperture aids low-light performance, but the lens is heavy and requires a tripod for handheld use. Build quality is robust, typical of Leica's R-series, though autofocus is absent, demanding manual focus skill. It suits wildlife and sports photographers who prioritize optical excellence and can manage the weight and manual operation.
