Overview

The Olympus Zuiko Digital ED 50-200mm f/2.8-3.5 SWD is a robust telephoto zoom for Four Thirds, offering a 100-400mm equivalent range. Optically, it delivers excellent sharpness, especially at f/4, with low chromatic aberration and vignetting. Build quality is high with dust/splash-proof construction, but the non-internal zoom extends considerably and sucks in air, raising dust concerns. The tripod collar is detachable but can cause balance issues. It lacks image stabilization and a focus limiter. Suits users with stabilized bodies needing a fast, durable telephoto zoom.
