EOS R SYSTEM

Reimagine Optical Excellence

Marking a new chapter in the history of EOS, the EOS R system is built for imagemakers who demand high-performance capture, a full-frame sensor and excellent ergonomics. A 54mm diameter lens mount enables RF lenses to have large rear elements, while a mirrorless design brings them closer to the sensor for bright, sharp and compact lens designs. A 12 pin electronic connection delivers fast communication between the camera and the lens, facilitating a versatile and powerful system. Plus, with a variety of mount adapter options, it’s easy to incorporate your EOS R system into an EOS system and expand your creative opportunities.

NEW RF Mount

At the heart of the EOS R system lies the amazing RF mount. It’s newly designed to deliver the ideal combination of speed, durability and flexibility in optical design for excellent performance and future system expansion, plus compatibility with EF and EF-S lenses*.

54mm Large Diameter and Short Back Focus

The large diameter and decreased distance between the rear lens element and sensor enable a compelling combination of image quality, performance and compact lens design. The new RF mount retains the same, large 54mm diameter as the current Canon EF mount, but thanks to the EOS R camera’s mirrorless structure, the rear lens element can be much closer to the image plane. This combination opens up a number of possibilities. The rear element of RF lenses can be larger in diameter, improving image quality at the corners and outer edges of the frame. Larger rear elements mean front elements can be smaller, meaning less strong refracting and bending of light rays within the lens, enhancing optical performance. Most importantly, the EOS R system opens the door to the future. It unlocks more freedom and flexibility in lens designs, allowing faster lenses with increased optical performance in more compact forms than before.

20mm Flange Focal Distance

The RF mount is mounted just 20mm from the image sensor. This provides flexibility for future lens designs and the durability needed for professional, real-world operation, even when using super telephoto lenses.

High-Capacity & High-speed Data Transmission

Data Transmission through 12 pin Electrodes

A 12 pin connection between the camera and lens means communication at a higher speed with larger amounts of data transfer, enabling incredibly fast AF, high IS and image optimization. It’s a system designed to expedite operations that’s ready for future expansions.

Compatibility with EF/EF-S Lenses

Mount adapters deliver seamless connections between the EOS R camera and EF and EF-S lenses with all functions intact. Offering L series level weather and dust sealing, they are even compatible with EF extenders like the Extender EF 1.4x III to extend your camera’s optical reach. With an entire arsenal of EF and EF-S lenses at your disposal, these mount adapters ensure endless creative possibilities for the EOS R camera.

Drop-in Filter Mount Adapter EF-EOS R

The Drop-in Filter Mount Adapter EF-EOS R enables compatibility with EF and EF-S lenses and includes drop-in filter capability for use with circular polarizing filters or variable ND filters. This enhancement enables compatibility with numerous lenses regardless of their front diameter, and makes filter use possible with lenses like the ultra wide EF 11–24mm f/4L USM lens or the tilt-shift TS-E 17mm f/4L lens which cannot accept a filter on the front.

EOS Full-frame

The EOS R camera helps expand the impressive lineup of Canon full-frame cameras such as the EOS-1D X Mark II, EOS 5DS, EOS 5DS R, EOS 5D Mark IV and EOS 6D Mark II to provide a wealth of amazing and powerful full-frame options. Using lenses at their original focal length, the EOS R benefits from a range of improvements made possible by the large physical size of full-frame sensors.

Shallow Depth of Field

Full-frame sensors offer shallow depth of field by design, making it easy to define depth of focus through aperture choice. These sensors deliver gorgeous and soft out of focus areas when shooting with large apertures.
