RF 2X EXTENDER Magnification: The extender provides a 2x magnification factor, which effectively doubles the focal length of the attached lens. For example, a 400mm lens becomes an 800mm lens.
Performance: It maintains a high level of image quality through advanced lens construction, and allows for seamless communication with the camera body, preserving full metering, autofocus, and Image Stabilization functionality.
Rugged design: The extender is built to withstand harsh shooting conditions. It features a dust- and water-resistant construction and a heat shield exterior to prevent performance degradation in high temperatures.
Optics: Special glass elements and lens coatings help to reduce ghosting, flare, and chromatic aberration.
