Overview

The MC Kaleinar-5N 100mm f/2.8 is a Soviet-era manual lens with robust all-metal construction and a compact, utilitarian design. It delivers excellent center sharpness wide open, with soft corners that improve by f/5.6–f/8, and produces pleasingly neutral color with slight warmth. Bokeh is superb, ideal for portraits and weddings, though flare can occur when shooting into light. Its smooth focus ring and tactile aperture ring appeal to photographers who value manual control and portability.
