Sears MC Auto 135mm F/2.8 Lens For Pentax K

The Sears MC Auto 135mm f/2.8 is a manual focus short telephoto prime lens produced for Pentax’s K-mount SLR system, distributed under the Sears house brand during the film SLR era. At 135mm with an f/2.8 maximum aperture, it delivers a classic short telephoto focal length well suited to portraiture, event, and general longer-reach photography, with useful light gathering capability and meaningful subject separation from the background at wider aperture settings. The MC designation indicates multi-coating applied to the optical elements to reduce flare and ghosting and improve contrast and color transmission, and the Auto designation confirms an automatic aperture mechanism that stops down to the set aperture only at the moment of exposure. Fully manual focus operation covers focus adjustment directly on the lens. Compatible with Pentax K-mount film and digital SLR bodies, and adaptable to mirrorless and other camera systems via third-party Pentax K-mount adapters.
