    Overview

    The Ricoh XR Rikenon 70-150mm f/3.5 is a telephoto zoom lens for Pentax K SLR cameras. Optical strengths include good sharpness at the center, but weaknesses include softness at the edges and some chromatic aberration. Build quality is solid with a metal barrel and smooth zoom/focus rings. It suits photographers seeking an affordable vintage zoom for casual use, though modern lenses offer better edge-to-edge performance.
