Created for R System cameras, RF lenses offer higher quality, speed, and operation thanks to outstanding optical technology and design. The EOS R System's unique 12-pin connection radically improves communication between the camera’s lens and body, making it faster than was previously possible. The RF lens mount is 54mm wide with a shallow depth from the mount to the sensor. The design allows lenses to be closer to the sensor, enabling the creation of faster, brighter, higher-quality optics with unsurpassed performance. RF lenses have improved video capabilities, plus neat touches like the control ring and more compact size.
