Overview

The Olympus OM Zuiko Auto-T 300mm f/4.5 is a solidly built manual-focus telephoto lens with a metal barrel and a built-in hood. It is sharp, with excellent detail and minimal distortion, and benefits from stopping down. Weaknesses include significant weight and size, making it cumbersome for travel. It suits photographers needing a long telephoto for landscapes or portraits, and on mirrorless cameras with focus peaking it becomes more usable.
