Canon Mount Adapter EF-EOS R

Canon Mount Adapter EF-EOS R - The EOS R System Mount Adapter ensures that the new Canon EOS R System is fully compatible with Canon EF and EF-S lenses, giving owners of the new system the ability to use their existing line of EF and EF-S lenses. Since EF-S lenses are designed for EOS DSLR cameras with an APS-C image sensor, when using these lenses with EOS R cameras via an adapter, the camera will automatically create cropped images with a resolution of 11.6 megapixels (in the case of the first cameras of this Canon EOS R range) that will match the smaller aspect ratio of EF-S lenses. All EOS R adapters have metal fasteners on both sides and are designed for professional use. They are guaranteed to be protected from dust and moisture, even when working in difficult conditions.
