Canon rf意思

"RF" in Canon RF refers to "R mount for Full-frame mirrorless cameras." It is a lens mount system designed for Canon's full-frame mirrorless cameras, which was introduced in 2018 with the launch of the Canon EOS R camera. The RF mount is characterized by a large diameter and short back focus distance, which allows for improved lens design and better image quality. The RF mount also features a 12-pin communication system that allows for faster data transfer between the lens and the camera, enabling advanced features such as fast autofocus and image stabilization.
