This JJC auto focus lens mount adapter allows a EF or EF-S mount DSLR lens from both Canon brand and third party brands such as Sigma, Tamron and Tokina to be used on a Canon RF mount full frame mirrorless camera. Electronic communication between an attached camera and lens is supported, enabling auto focus as well as auto exposure features. If an attached lens is capable of generating Exif metadata, this adapter is designed to transfer that information so that it can be saved with image files generated by the combined Canon EF or EF-S mount lens and Canon-RF mount camera.</br> </br> Made of aluminium alloy and premium brass, this adapter is durable while remaining lightweight, and an internal, matte black coating minimizes the appearance of reflections within the adapter barrel. To help reduce stress on the camera mount when placed on a tripod, the adapter includes a detachable tripod foot with 1/4 inch-20 threads.</br> </br>Product Highlights:</br></br> For attaching any EF/EF-S mount DSLR lens from Canon brand and third party brands such as Sigma, Tamron and Tokina to the Canon RF mount full frame mirrorless camera body such as Canon EOS R, R5, R6, RP</br> Contains no optical components </br> Maintains the original optical quality of the mounted lens</br> Retains full autofocus and image stabilization capabilities</br> Made of durable aluminium alloy and premium brass</br> Non-glare matte finish on the inside prevents reflections</br> Removable tripod foot comes with a 1/4 inch-20 tripod socket at the bottom</br> </br>Packaging includes:</br> </br>1.
