The Canon RF lens mount is a camera lens mount system designed for Canon's full-frame mirrorless cameras. Introduced in 2018, it features a larger diameter and shorter flange distance compared to the previous EF mount, allowing for improved optical performance and more versatile lens designs. The RF mount supports a wide range of lenses, including standard zooms, primes, and specialty lenses. Its electronic communication between the camera and lens enhances autofocus speed and accuracy, while also enabling advanced features like image stabilization and customizable lens controls.
