Overview
The Canon CN-E 20mm T1.5 L F Cinema Prime - EF Mount lens offers a compact, consistent lens design and proven Canon lens elements for performance and reliability in professional shooting environments. Intended for the working professional, the EF Cinema Prime CN-E 20mm T1.5 L F lens features markings on angled surfaces on both sides of the barrel, making it easy to read focus and aperture settings from behind or either side of the camera. Focus markings can even be switched from standard labeling to metric. The control rings are engineered to maintain the proper amount of resistance with consistent operating torque.
Designed to fulfill contemporary 4K production standards, it features a full frame image circle in a lightweight, compact design. This lens is ideal for any number of applications. It features an 11-blade aperture diaphragm for beautiful bokeh (background blur) and innovative glass construction that counteracts barrel expansion and contraction to avoid temperature-induced marking discrepancies.
Canon's brilliant Cinema Prime lenses offer spectacular optical performance for demanding high-end productions. Featuring a compact and consistent lens design, these lenses offer consistent form factors and markings optimized for motion picture production. Sharing the same gear position, diameter and rotation angle and front diameter, the lenses' compatibility with third-party accessories allows the user to easily change lenses without making adjustments to the rig setup.

High Resolution & Warm Colors
The lens features a large diameter aspheric lens and anomalous dispersion glass, working to deliver high contrast and sharp imaging from the center of the image to the outer edges. This helps bring out the high quality of 4K cinema images. The lens produces warm color tones that help to softly capture people’s facial expressions and enable better depiction of textures captured through the lens.
Fast Maximum Aperture
Operating at T1.5 helps the lens achieve a softer and greater bokeh, while allowing users to shoot brighter in low-light settings.
Unified Warm Color Balance within Canon Cinema Lenses
Canon’s color science has become highly refined over generations of lens designs, paying the closest attention to a pleasing skin tone reproduction. The CN-E 20mm T1.5 L F lens can be used interchangeably with other Canon Cinema lenses during the same production since they all have the same warm, cine-look color characteristics, making it easier to maintain consistent color when multiple lenses are used.
Minimized Focus Breathing
The lens has been designed to minimize variations in the angle of view while focusing, a phenomenon known as focus breathing. This feature is extremely important while focus pulling, where changes in the angle of view due to focus breathing could become apparent to the viewer.
Support for Full Frame Cameras
The CN-E 20mm T1.5 L F Cinema Prime Lens covers a 35mm Full Frame sensor and features a genuine Canon EF mount, compatible with all Cinema EOS camera models, including Full Frame models such as the EOS C700 FF digital cinema camera, as well as other top-quality full frame cameras. With a Super 35mm camera, the lens can be used as an approximately 29.2mm equivalent lens (35mm film equivalent) for use in a wide range of shooting situations, helping users produce premium-quality images.
The EF mount features electronic contacts on both the lens and camera sides that allow direct communication between each device. This communication allows lens metadata including aperture to be displayed in the viewfinder. Both the T-stop and the focus position are recorded in the video file.
11-Blade Iris
The CN-E 20mm T1.5 L F Cinema Prime Lens features an 11-blade iris. This produces artistic and beautiful out-of-focus areas, creating a more three-dimensional bokeh with the deeper depth of field that a super wide angle lens can offer, broadening the range of visual expression. The use of an odd number of blades also helps reduce flaring of specular highlights. Additionally, the iris ring is mechanically controlled with no click stops for smooth exposure adjustments while recording.
Reliability & Operability
Designed to meet the needs of professional cinematographers, the CN-E 20mm T1.5 L F Cinema Prime Lens features a uniform 114mm front diameter, 300° rotation angle, and gear position on the focus and iris rings (making lens changes quick and convenient) across the entire Cinema Prime Lens series. The control rings work to maintain the right amount of resistance and operating torque in order to help provide the camera operator or assistant with a consistent feel and predictable lens operation.
105mm Front Threads for Screw-on Filters
To allow for additional ease of use and flexibility, the lens features threading on the front of the lens to accommodate 105mm screw-on filters. This feature allows the camera operator to add filters over the lens without the need for a mattebox to be attached to the camera system helping to provide flexibility in filter choice as well as the ability to shoot in a more streamlined format.
Dust & Water-Resistant
The lens is equipped with gaskets and seals for dust- and water-resistant operation, helping to make them ready for shooting, even in severe conditions.
Clearly Visible Focus Scale
Distance indicators are displayed on both sides of the lens. To improve visibility in nighttime and dark area shooting, indicator markings with phosphorescent paint have been adopted for the front barrel (for right-side viewing).
Communication with Cinema EOS Cameras
The CN-E 20mm T1.5 L F Cinema Prime Lens functions seamlessly with Cinema EOS cameras, allowing you to take full advantage of the camera’s features and functionality.
Peripheral Illumination Correction
This image correction feature can be turned on or off based on registered lens information.
Lens Information Display/Recording
Lens information can be displayed on the viewfinder of the camera, and metadata such as lens name and position can be recorded in the image.
Dual Pixel Focus Guide
Lens position data and Dual Pixel CMOS AF can combine to display the focus position on the user interface.
