CN‐E 20mm T1.5 EF Lens
Intended for the working professional, the EF Cinema prime CN-E20mm T1.5 L F lens has markings on angled surfaces on both sides of the barrel, making it easy to read focus and aperture settings from behind or from 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.
- T1.5 maximum aperture
- 11-blade aperture
- Supports 4K capture
- Dust and water resistant
Fulfills 4K Production Standards
Designed to fulfill contemporary 4K production standards, it features a full-frame imaging circle in a lightweight, compact design- this phenomenal lens is also perfect for any number of applications. It also features an 11-blade aperture diaphragm for beautiful background blur and innovative glass construction that counteracts barrel expansion and contraction to avoid temperature induced marking discrepancies.
Cinema Prime Lenses
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 crews to easily change lenses without making adjustments to the rig setup.
Outstanding Optical Performance to Support 4K Cameras
The CN-E 20mm T1.5 L F Cinema Prime Lens is designed to provide outstanding optical performance and is capable of full 4K-Resolution performance. Whether you’re shooting in HD with a Canon EOS DSLR camera or in 4K using an EOS C700 Digital Cinema Camera, the CN-E 20mm T1.5 L F will help you to create a cinematic masterpiece by providing superb image quality, contrast and colour fidelity.
High Resolution and Warm Colours
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 colour tones that help to softly capture people’s facial expressions and enable better depiction of textures captured through the lens.
Fast T Number
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 Colour Balance within Canon Cinema Lenses
Canon’s colour 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 both have the same warm, cine-look colour characteristics – making it easier to maintain consistent colour 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 35mm full-frame sensor and features a genuine Canon EF mount and works with all Cinema EOS camera models, including full-frame models such as our new 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 has electronic contacts on both the lens and camera sides that allow direct communication between each device. This communication allows lens metadata including T-numbers to be displayed in the viewfinder. Both the T-number and the focus position are recorded in the video file.
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.
Outstanding Operability and Reliability
Designed to meet the needs of professional cinematographers, the CN-E 20mm T1.5 L F Cinema Prime Lens features a unified front diameter (114mm), rotation angle (300°) and gear position on the focus and iris rings (making lens switching quick and convenient) across our 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 Lens Threading 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 matte box 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 and 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
