The RF Prime series of cinema lenses from Canon has been designed for outstanding optical performance rendering crisp images with natural, rich contrast. This series includes seven lenses, ideal for shooting 8K as well as HDR, and represent Canon’s first cinema lenses to have a native RF mount. This lens series ushers in the RF lens communication to fully manual cinema glass, ideal for shooting with RF-mount cameras including third-party cameras that utilize a native RF mount.

The RF Prime series covers seven focal lengths, with lenses at 14, 20, 24, 35, 50, 85, and 135 millimeters and share a common gear positioning and diameter across all seven lenses. The entire lens series provides for reliable and consistent usability including a smooth focus rotation and sizing, with the same front diameter and rotation across all focal lengths.

RF Mount Cinema Lenses for Professional Productions
Step into cinematic filmmaking with a range of RF Prime lenses that offer ultra-fast, real-time metadata capture plus all-new features such as in-camera electronic distortion correction.


8K Optical Performance with Canon Cinema EOS Color Science
Rated for 8K HDR image capture the lenses produce amazing color rendition and detail, with sharp resolution from the center to the outer edges. An 11-blade iris creates soft, beautiful light rays and stunning depth-of-field falloff. The lenses render the beautiful and warm color tones synonymous with Canon’s cinema lens family.

Canon’s advanced optical technology and lens coatings have combined to achieve 8K optical performance. Various types of aberrations have been corrected to achieve beautiful imagery from the center of the image out to all edges.

All of Canon’s cinema lenses have been designed with a consistent warm color balance that expresses skin tones beautifully, making them ideal for capturing subject textures.  Color reproduction is also consistent when lenses are interchanged, which can help minimize corrections in post.

HDR video offers an expanded tonal range that represents the visual expression close to its natural image.  Our 8K-compatible chromatic aberration correction which can reduce color bleeding, and the light-shielding design and optimized coatings reduce ghosting and flaring.

The inner focus system can reduce focus breathing, giving great stability when framing a shot.

The 11-blade iris gives the lenses a natural bokeh effect that is almost circular from maximum to the minimum aperture.  The odd number of blades diffuse the glow of high luminance subjects for softer imaging.


Full-Frame Creativity
The RF Prime lenses are designed for Full-Frame, Large-Format cameras, enabling impressive images using bokeh with a shallow depth of field.


Mechanical Precision in a Compact Design
With a smooth and consistent 300-degree focus rotation, consistent gear positions / front diameter and a compact, robust and drip-proof design, the RF prime lenses offer a no-compromise, lightweight solution for professional productions.


Refined ergonomics, redefined handling
Confidently secure your lenses without the need for an adapter when utilizing RF mount Cinema EOS cameras or compatible third-party cameras. With a newly-developed fixed ring design, RF Prime lenses make handheld operation more comfortable, intuitive, and efficient.

Distortion Correction
High-speed data transfer makes it possible to instantly transfer lens metadata to the camera, enabling distortion correction according to lens characteristics when shooting video with compatible cameras*.
