Sigma 70-210mm f4.5 with Konica AR Mount (AS-IS)

The Sigma 70-210mm f/4.5 is a manual focus telephoto zoom lens produced for Konica’s AR mount SLR system. Covering a focal range from 70mm to 210mm with a constant f/4.5 maximum aperture throughout, it addresses a practical telephoto zoom range well suited to portraiture, wildlife, sports, and general longer-reach photography, with the constant aperture maintaining consistent exposure and depth of field characteristics across the entire zoom range. Fully manual operation covers both focus and aperture adjustment directly on the lens. Sigma was a well-established third-party lens brand producing alternative optics across multiple mount systems during the film SLR era. Compatible with Konica AR-mount film SLR bodies, and adaptable to mirrorless and other camera systems via third-party Konica AR mount adapters. This listing is offered as-is, and the functional condition of the lens should be verified before purchase.
