Overview

The Yashica Auto Yashinon 50mm f/2 is a vintage M42 lens with all-metal build and solid handling. Optically, it offers pleasing bokeh and good center sharpness when stopped down, but wide-open corners are soft and the focal plane is curved, causing corner softness at infinity. Flare is pronounced in backlight, which some may like. It struggles with focus on adapted rangefinders due to lack of coupling. Best suited for those seeking a cheap vintage character lens for stopped-down use on compatible SLRs or mirrorless cameras.
