EF to RF Auto-Focus Adapter with Control Ring

This EF-EOSR adapter enables Canon EF and EF-S lenses to be used on EOS R and RF-mount full-frame mirrorless cameras. Constructed from ABS plastic and metal, it measures approximately 8 x 7 x 3 cm (3.1 x 2.7 x 1.1 inches) and weighs just 95 g (0.2 oz). The lens-mount outer diameter is approx. 65 mm (2.5 inches), and the camera-mount diameter is approx. 50 mm (1.96 inches). It features gold-plated electrical contacts for reliable data transmission, a built-in control ring for manual adjustments, and a 1/4-inch tripod screw thread for stable mounting. Includes one wrench for secure installation/removal, one cleaning cloth (random colour), and a user manual. The adapter fully supports autofocus (AF), in-lens image stabilisation (IS), electronic aperture control, and EXIF metadata transmission — ensuring seamless communication between lens and camera body. For optimal AF performance, ensure the lens is set to AF mode after installation. Designed for precision fit and long-term reliability, the adapter housing is rust-resistant and impact-resistant, with fine craftsmanship and durable surface finish.
