    80–200mm · f/4.5

    Overview

    The SMC Pentax-M 80-200mm f/4.5 is a solidly built all-metal zoom lens with a rubber grip, though the aperture ring feels thin. It is adequately sharp, with forum reports of softness wide open not observed in practice, and can produce swirly bokeh. Weaknesses include purple fringing in some images and a tendency for cool color rendition. The push-pull zoom is convenient, but the lens is front-heavy on compact bodies. It suits budget-conscious shooters who value versatility over prime-level performance.
