The standard Mount Adapter EF-EOS R allows EF-S and EF lenses to be used on EOS R cameras seamlessly. Photographers who already have a collection of EF-S or EF optics can invest in the EOS R System confidently, knowing their existing lenses will work as expected.
The Canon Mount Adapter EF-EOS R is an essential rental item for professional photographers and videographers who are transitioning to, or simultaneously shooting with, the new EOS R mirrorless system while maintaining an investment in Canon's extensive EF and EF-S DSLR lens library. Hiring this adapter is far more economical than purchasing it if you only need it for a specific project or rental period. It allows you to utilize your existing, high-quality EF glass—including specialized tilt-shift, macro, and cinema lenses—on the R-series body with full electronic communication, including complete autofocus and aperture control, ensuring your lens collection remains fully usable without sacrificing performance.
