Olympus 135mm f3.5 E.Zuiko Auto-T Lens

The Olympus 135mm f/3.5 E.Zuiko Auto-T is a manual focus telephoto prime lens built for Olympus’s OM-mount SLR system. At 135mm with an f/3.5 maximum aperture, it delivers a classic short telephoto focal length well suited to portraiture, event, and general longer-reach photography, with useful subject separation from the background at wider aperture settings. The E.Zuiko designation refers to the optical formula, with the E indicating a five-element construction, and the Auto-T designation identifying it as a telephoto lens within the Zuiko lineup with an automatic aperture mechanism that stops down to the set aperture only at the moment of exposure. The Zuiko optical series developed a strong reputation for image quality during the OM-system era. Compatible with Olympus OM-mount film SLR bodies, and adaptable to mirrorless and other camera systems via third-party OM-mount adapters.
