Overview

The Rikenon 55mm f/1.4 Auto is a heavy, solidly built M42 lens made by Tomioka Optical. It feels mechanically tight and smooth. Optically, it delivers sharp images with smooth bokeh and round highlights wide open, though bokeh is not particularly large. Focusing requires care, especially at close distances and wide apertures. It suits photographers who enjoy a deliberate, manual shooting experience and value build quality over modern optical perfection.
