Unique and ground-breaking designs
The RF lenses differ from EF lenses in that they have been designed from the ground up for the new full-frame mirrorless Canon EOS R body. They offer higher levels of image quality thanks to the nature of the larger mount and flange back design, while processing speeds have also been significantly raised.
Increasing the communication speed was instrumental in offering a higher level of overall camera and lens performance. With the EOS R System, in addition to the optical information, the lens also holds optical correction data. This includes the Digital Lens Optimizer, which was previously stored in the camera’s memory.
“The faster the communication speed, the more possible it is to send this data to the camera in a shorter time,” explains Senior Engineer Akihiro Kawanami. “In other words, the system can start up even faster after replacing the lens. In addition, it is possible to improve various functions such as image stabilization by coordinating the lenses and camera.”
