Characterized by its speed and portrait-length field of view, the Primoplan 75mm f/1.9 from Meyer-Optik Gorlitz is a sophisticated, yet simple prime for Leica M-mount rangefinder cameras. The bright f/1.9 maximum aperture pairs well with the short telephoto focal length to allow working with shallow depth of field and selective focusing techniques, and the fast aperture also benefits working in difficult lighting conditions. Its manual focus design further offers control when focusing down to 2.5', and a 14-blade diaphragm contributes to a smooth bokeh quality. The five elements, four groups optical design makes use of Schott glass for a high degree of clarity, and an O'Hara Anti Reflex Coating has also been applied to limit flare and surface reflections for improved contrast and color accuracy. Additionally, the lens features an anodized aluminum housing that is durable, lightweight, and contributes to smooth, silent focusing performance.
