    Overview

    The Olympus 100-400mm F5.0-6.3 IS offers impressive telephoto reach (200-800mm equivalent) in a relatively compact, weather-sealed package. Optical strengths include sharp images even at high ISO and compatibility with teleconverters. Weaknesses include a slow maximum aperture requiring high ISOs and some hunting in low contrast. Build quality is excellent with smooth manual focus, but the lens is larger and heavier than its Panasonic rival. It suits wildlife and sports photographers seeking an affordable, portable super-telephoto.
