Description — Olympus EC-20
The Olympus Digital EC-20 is a prime teleconverter built for the Four Thirds DSLR camera system, mounting via the Olympus OM lens mount. It is intended for use with compatible DSLR bodies and supports both auto and manual focus, preserving autofocus capability when paired with supported lenses. The teleconverter weighs 280g, making it a substantial optical accessory that contributes meaningful mass to the overall camera-and-lens setup — something to consider for extended shooting sessions. Image stabilization is not present in the EC-20 itself, so photographers relying on optical stabilization will need to source that from their host lens or camera body.
As a native Four Thirds accessory on the Olympus OM mount, it integrates directly with the existing ecosystem without requiring third-party adapters or workarounds. The EC-20 is classified as a telephoto type accessory, oriented toward extending reach for distant subjects within the Four Thirds system.
