50mm · f/2
The Ricoh XR Rikenon 50mm f/2 lens is praised for its sharpness and smooth bokeh, earning the nickname "poor man's Summicron". Optical strengths include excellent contrast and accurate color rendition. Weaknesses include significant barrel distortion. Build quality varies: early metal versions are well-constructed, while later plastic versions are lighter but less durable. The lens handles well, with a smooth aperture ring. It suits budget-conscious photographers seeking vintage character, especially on mirrorless cameras.
