Leica Summicron 50mm f/2 Dual Range Prime lens

Leica Summicron 50mm f/2 Dual Range – a classic M-mount prime with a unique dual focusing range. Standard focus from 1 m to infinity; with the close-focus attachment (“eyes”) to about 0.48 m, ideal for close-ups with the coupled rangefinder. Fast f/2 for light gathering and shallow depth of field. Optical construction: 7 elements in 6 groups; 10-blade aperture for smooth bokeh. Aperture f/2–f/16, manual focus. Filter size E39. Compatible with Leica M cameras; close-focus function requires the attachment. Excellent for reportage, street photography, and portrait."
