Canon CN-E 20mm T/1.5 L F

Announced in March 2018, the Canon CN-E20mm T1.5 L F is a full-frame 20mm cinema prime with a native Canon EF mount. It fills the gap between Canon’s 14mm and 24mm Cinema EOS primes, combining a very wide field of view with a fast T1.5 aperture. That makes it especially useful for interiors, architecture, music videos, commercials, gimbal work, establishing shots and low-light scenes where a wide lens still needs strong control over exposure and depth of field.

T1.5 speed, manual cine mechanics and 0.30 m MOD

This is a fully manual cinema lens with no autofocus and no optical image stabilization. Focus and iris are operated mechanically, with standardized cine gearing and a 300° focus rotation for precise marks and repeatable pulls. Minimum object distance is 0.30 m, allowing the camera to move close to foreground subjects while still retaining a broad view of the environment.

Canon uses an 11-blade iris and a de-clicked mechanical aperture ring for smooth exposure changes during a take. The lens also minimizes focus breathing, helping preserve the angle of view during focus pulls. At approximately 1.2 kg, it has enough mass for stable cine operation while remaining manageable on professional shoulder, tripod and gimbal builds.

Full-frame 4K optics and consistent Cinema EOS color

Canon designed the lens for 4K production with a full-frame imaging circle. Large-diameter aspherical elements and anomalous-dispersion glass help control distortion, chromatic aberration and loss of resolution toward the edges of the frame. Canon also tuned the color reproduction to match its other Cinema EOS primes, making it easier to intercut focal lengths within the same project.

On a 36 × 24 mm sensor, Canon specifies an angle of view of approximately 84.0° × 61.9°. The EF mount includes electronic contacts that can transmit lens metadata, including T-number and focus position, to compatible Cinema EOS cameras.

114mm front, 105mm filters and rental setup

The lens uses the same 114mm front diameter as Canon’s other Cinema EOS primes, which helps standardize matte-box and clip-on accessory setups. Unlike the CN-E14mm, the 20mm also accepts 105mm screw-in filters, giving productions another option for ND, diffusion or creative filtration.

Our rental set includes the Canon CN-E20mm T1.5 L F with native EF mount, front and rear caps and a carrying case.
