Overview

The Olympus Zuiko Digital 2.0x Teleconverter EC-20 doubles focal length for Four Thirds lenses, offering a compact, high-performance design. Optically, it extends reach but typically reduces maximum aperture and may degrade sharpness, though specific test data is not provided. Build quality is solid, with a compact form that maintains mobility. It suits photographers needing cost-effective telephoto reach or macro magnification, particularly with Zuiko lenses.
