This adapter ensures full electronic communication between the lens and camera, allowing autofocus, aperture control, and image stabilization functions to operate correctly. Made from a durable white polycarbonate housing that matches the aesthetics of professional Canon equipment, the adapter features a secure locking mechanism with a release button for safe attachment and removal of the lens. The internal design includes electrical contacts that transmit all necessary data signals without loss, supporting lens-specific corrections and metadata recording. With dimensions of approximately 80 mm in diameter and 25 mm in thickness, the adapter adds minimal bulk while maintaining the required correct flange distance for precise focusing. Weighing about 120 g, it provides a balanced feel on the camera. The adapter supports all shooting modes, including manual, aperture priority, shutter priority, and program auto, as well as video functions. It works with lenses with maximum apertures ranging from f/1.2 to f/32 and is compatible with most EF and EF-S optics. The mount features brass plating on critical contact surfaces for increased durability and reliable electrical connection over extended use. This product offers a practical solution for photographers transitioning to RF-Mount systems who wish to continue using their existing EF lens collection without loss of functionality.
