Vivitar MC 70-210mm f/4.5-5.6 Lens Pentax K-Mount

The Vivitar MC 70-210mm f/4.5-5.6 is a manual focus telephoto zoom lens produced for Pentax K-mount film SLR cameras. The MC designation indicates multi-coating on the optical elements, intended to reduce flare and ghosting and improve contrast and color transmission compared to uncoated or single-coated alternatives. Covering a focal range from 70mm to 210mm with a variable maximum aperture, it addresses a practical telephoto zoom range suited to portraiture, wildlife, sports, and general longer-reach photography. Fully manual operation covers both focus and aperture adjustment directly on the lens. Vivitar was a well-known third-party lens brand active during the film SLR era, producing a wide range of alternative optics across multiple mount systems at accessible price points. Compatible with Pentax K-mount film SLR bodies, and adaptable to mirrorless and other camera systems via third-party Pentax K-mount adapters.
