    Overview

    The Ricoh Rikenon 50mm f/1.7 is a sharp, fast prime lens from the 1980s, known for excellent optical performance even wide open. It is not multi-coated, so flare can be an issue without a hood. Build is mostly plastic with a metal rear mount; the 'P' version has an auto-aperture pin that may need removal for use on Pentax bodies. It suits budget-conscious photographers seeking a sharp 50mm, especially those willing to modify the lens for compatibility.
