The RF lens mount enables a radical new optical design, allowing large lens elements to be placed as near to the sensor as possible, allowing light to hit the sensor straight on. This reduces optical aberrations, increasing the quality of the image.
The mount’s short back focus and wide 54mm mount diameter has made it possible for Canon optical engineers to have a new degree of freedom in order to create a new generation of optics – it provides an ideal balance between reducing the size of the system, high-quality images and high-spec performance.
Canon is proud to announce six full-frame RF lenses are currently in development for release in 2019, that will expand the EOS R System to open up new shooting possibilities.
EOS R System mount adapters are unique and offer additional creative control, enabling photographers and filmmakers to use their existing EF and EF-S lenses with full compatibility and no loss in performance.
