55mm · f/1.8
The Yashica Auto Yashinon 55mm f/1.8 is a vintage M42 lens with attractive cosmetics and solid performance. Wide open, it offers good central sharpness and a vintage character with pleasant bubble bokeh, though corners are soft and some chromatic aberration is present. Stopped down to f/5.6–f/8, it becomes very sharp across the frame. Build quality is good, but the metal frame can produce flare in backlit conditions. It suits photographers seeking a classic look with usable wide-open performance and excellent stopped-down sharpness.
