8K Optical Performance with Canon Cinema EOS Color Science
The lenses produce superb color rendition and detail, with sharp images from the center to the outer edges, rated for 8K HDR capture. An 11-blade aperture creates soft, beautiful light rays and stunning depth-of-field falloff, while an internal focusing system delivers minimized focus breathing and excellent parfocal performance. 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 through the zoom range. 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 reduce post-production work.
HDR video offers an expanded tonal range that represents the visual expression close to its natural image. Our 8K-compatible chromatic aberration correction reduces color bleeding, and the light-shielding design and optimized coatings reduce ghosting and flaring.
The inner focus system reduces focus breathing, giving greater stability to 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.
Constant T2.4 throughout the zoom range
The CN-E20-50MM T2.4 L F / FP and CN-E45-135MM T2.4 L F / FP are Canon's first full-frame cinema zoom lenses, offering a constant maximum T-stop value of T2.4 across the zoom range. Large aperture lenses allow for more light to reach the sensor, and the light transmission remains constant throughout the zoom range. With consistent light throughout the zoom range offered by both lenses, these two are a great pair for high-quality results no matter the production.
Designed for Full Frame Cameras
The CN-E20-50MM T2.4 L F / FP and CN-E45-135MM T2.4 L F / FP are designed for Full-Frame, Large-Format cameras, enabling impressive images using bokeh with a shallow depth of field.
Advanced Lens Metadata Support
The Flex Zoom series lenses are compliant with a wide range of communication standards thanks to the versatile lens-to-camera communication function including Cooke /i Technology™ (PL mount) and EF mount. This will enable you to display or record lens metadata as well as utilize camera functions such as aberration correction, peripheral illumination correction and focus guide function with compatible cameras.
Available in EF Mount or Cooke/i Technology™ PL Mount Options
Cinema Style Operability
Both the CN-E20-50MM T2.4 L F / FP and CN-E45-135MM T2.4 L F / FP lenses share the same design with consistent front diameter, gear positions and gear rotation angles. Weighing under 8 pounds and measuring under 10 inches long, the lenses also feature focus, zoom, and iris rings with industry standard gears and 0.8mm pitch to suit many third party follow focus accessories. The lenses feature luminous (glow in the dark) metric and imperial markings for easy operation in low light. Built for longevity, the premium design and outstanding optics and components, offer quick and precise operation, with durability ideal for professional video productions.

Mount Adapter EF-EOS R 0.71x
Canon's innovative new EF - RF optical adapter, the Mount Adapter EF-EOS R 0.71x, converts light transmission from full-frame to the Super 35mm image format. It extends the angle of view and optical sensitivity, while seamlessly integrating with the camera's optical corrections. This unit greatly expands the list of compatible lenses by including Canon's renowned line of EF lenses. In addition to the flanges of the RF mount, four screws securely attach the adapter to the EOS C70 camera. Once mounted, the adapter maintains a similar angle of view of your full frame lenses on the Super 35mm sensor, while boosting the speed of the attached lens. The adapter also carries all EF information through to the RF contacts, so, on certain EF lenses**, full DPAF and metadata will be available with EOS C70 camera, working much as they do on a native EF mount. **As of September 25, 2020, the following lenses are compatible: the EF16-35mm f/2.8L III USM (released in October 2016), the EF24-70mm f/2.8L II USM (released in September 2012), the EF24-105mm f/4L IS II USM (released in November 2016). Canon plans to gradually expand the list of compatible lenses by providing free-of-charge firmware updates. EF lenses are still compatible with the camera, but Canon recommends that firmware updates be installed in order to effectively utilize functions which link the camera and lens.
