Description — Olympus MC-20
The Olympus M.Zuiko Digital 2x Teleconverter MC-20 is a Micro Four Thirds mount teleconverter built for the mirrorless camera system. Weighing just 150g, it adds minimal bulk to a telephoto setup while providing extended reach in the telephoto focal length range. One of its key practical advantages is its autofocus support — the focusType is confirmed as Auto, so shooters are not forced into manual focus when the converter is in use.
The MC-20 uses a Micro Four Thirds lens mount on both the camera and lens sides, ensuring a native, electronically communicative connection with compatible MFT bodies and lenses. It carries no filter thread and no built-in image stabilization, so those features remain the responsibility of the host lens. For photographers working within the Micro Four Thirds ecosystem who want to push their telephoto range further while keeping autofocus active, the MC-20 offers a mount-native, lightweight solution.
