Canon has been at the forefront of imaging technology for over 80 years and continues to innovate. In 1987, Canon introduced EF lenses and the first EOS Camera, which featured the world’s first fully electronically controlled lens mount: the EF Mount. In the digital era that followed, the EOS System continued to evolve and meet the demands of each generation. During that time, the EF Mount and EF lenses became a core part of the Cinema EOS System and other Canon imaging technologies, including ultra-high-sensitivity cameras. Renowned for their outstanding performance and reliability, EF lenses are widely used throughout the industry.
In 2018, we proudly introduced the EOS R System, making its debut with the EOS R mirrorless camera and RF lenses. The new system, with its large-diameter mount, facilitates ideal lens design and realizes sophisticated data transmission between the body and lens to achieve unprecedented image quality, enhanced usability and expanded photographic possibilities. Even in the digital era, the essence of imaging is defined by the lens’s ability to capture light. Canon will continue to elevate its unrivaled optical technology and deliver a thoroughly advanced imaging system, revolutionizing the future of visual expression.

The EOS R System brings to life a unique synergy between the camera and lens through the RF mount. At the core of this breakthrough design is the large 54 mm diameter inherited from the EF Mount and a short back focus made possible through the use of mirrorless technology. RF lenses achieve superlative optical performance afforded by the RF Mount and feature a newly added control ring while maintaining a simple design and ease of use.
The EOS R System also benefits from compatibility with EF and EF-S lenses through innovative mount adapters that allows users to harness the full potential of their existing lenses. The combination of further-refined superlative Canon technology—Dual Pixel CMOS AF and DIGIC image processors—realizes wide area AF, faster autofocusing and previously unattainable AF shooting in extreme low-light conditions. The EOS R System further improves image quality while maintaining usability through the high-speed transmission of large volumes of data between the camera and lens.

In 2019 Canon launched the EOS RP, joining the EOS R and four RF lenses released in 2018. What’s more, Canon is pushing forward with the development of six new RF lenses scheduled for release this year. Canon will continue to expand the EOS R System lineup to meet the diverse needs of today’s users.
