50mm · f/2
The Ricoh Rikenon 50mm f/2 is a budget vintage lens often called a 'poor man’s Summicron'. Optically, it delivers pleasing bokeh and sharpness wide open, though barrel distortion is notable. Build quality varies: early Tomioka-made versions have metal construction, while later Nitto-made ones use more plastic. The lens is very light (~135g) and compact. It suits photographers seeking a cheap, characterful 50mm for casual shooting, especially on mirrorless cameras.
