A versatile blend of a long focal length and a compact stature, the black Summarit-M 90mm f/2.4 from Leica is a short telephoto prime designed for M-mount rangefinder cameras. Based on a classic spherical optical design, this 90mm f/2.4 offers clean and natural rendering with notable color accuracy and clarity. Its manual focus design permits working with subjects as close as 3' away, and included with the lens is a screw-on lens hood to shield the front element and prevent lens flare and ghosting. Spherical optical design with five elements in four groups contributes to a high degree of sharpness and clarity. Manual focus design permits working with subjects as close as 3' away with a maximum reproduction ratio of 1:7.8. Eleven-blade diaphragm contributes to a smooth bokeh quality to suit selective focus and shallow depth of field imagery. Screw-on lens hood is included and the lens also has front filter threads to accept 46mm filters.
