Ricoh 50mm F/2 Rikenon XR L Manual Focus Lens For Pentax K Mount Review

The Ricoh 50mm F/2 Rikenon XR L is a legacy manual focus prime for Pentax K mount cameras. Originally part of Ricoh's XR lens lineup from the film era, it offers classic 50mm standard focal length optics at a modest f/2 maximum aperture. This particular example comes from KEH in Excellent condition with noted front ring damage, priced at $48.

As a vintage manual lens, the Rikenon XR L appeals to photographers interested in adapting legacy glass to modern mirrorless bodies or using it on Pentax DSLRs. At 50mm and f/2, it sits in the middle ground between faster f/1.4 primes and slower budget options. The KEH listing indicates solid cosmetic and functional condition despite the ring damage, making it an inexpensive entry point into manual focus shooting or vintage lens experimentation. Build quality from this era tends toward all-metal construction, and 52mm filter threads are a common size.
