What Is Acanon Rf Lens Mount ?

The Canon RF lens mount is a lens mount developed by Canon for its full-frame mirrorless cameras. It was introduced in 2018 with the launch of the Canon EOS R camera. The RF mount features a larger diameter than Canon's previous EF mount, allowing for faster and more accurate autofocus performance. It also has a shorter flange distance, which means that lenses can be designed to be smaller and lighter while still maintaining high image quality. The RF mount has a total of 12 electrical contacts, which allows for more advanced communication between the camera and lens, including the ability to correct for lens aberrations in-camera. Canon has released a range of RF lenses for the system, including wide-angle, standard, and telephoto zooms, as well as prime lenses. The RF mount is not compatible with Canon's EF or EF-S lenses without an adapter.

3、 Compatibility of RF lenses with Canon cameras

What is a Canon RF lens mount?

The Canon RF lens mount is a relatively new lens mount introduced by Canon in 2018. It is designed specifically for Canon's full-frame mirrorless cameras, such as the Canon EOS R and EOS RP. The RF mount features a larger diameter than Canon's previous EF mount, allowing for faster and more accurate autofocus, as well as improved image quality.

Compatibility of RF lenses with Canon cameras:

RF lenses are only compatible with Canon's full-frame mirrorless cameras that feature the RF mount. This means that they cannot be used with Canon's DSLR cameras that feature the EF mount. However, Canon offers an EF-EOS R mount adapter that allows EF lenses to be used with RF mount cameras.

The RF mount has quickly gained popularity among photographers due to its improved performance and image quality. Canon has also been steadily releasing new RF lenses, including a range of high-quality prime and zoom lenses. As of 2021, there are over 20 RF lenses available, with more expected to be released in the future.

In conclusion, the Canon RF lens mount is a new lens mount designed specifically for Canon's full-frame mirrorless cameras. RF lenses are only compatible with RF mount cameras, but an adapter is available to use EF lenses with RF mount cameras. The RF mount has quickly gained popularity among photographers due to its improved performance and image quality, and Canon continues to release new RF lenses.

4、 Comparison of RF lenses with other mirrorless mounts
