The Olympus MC-20 M.Zuiko Digital 2x Teleconverter doubles the magnification of select Olympus lenses, dramatically boosting the apparent focal length of those lenses with a minimal increase to the size or weight of the camera and lens combination. Inside this teleconverter, nine optical elements including one HR lens, in four groups with Olympus's ZERO coating help to ensure clarity and color fidelity while reducing ghosting and flare. When used with the Olympus M.Zuiko Digital ED 300mm f/4 IS PRO Lens, this teleconverter also enables tele-macro photography with up to 0.96x magnification as well as up to +5 EV stops of image stabilization with the Olympus OM-D E-M1X Mirrorless Digital Camera.
