The New RF Mount, CN-R20mm T1.5 L F is a great choice for a wide-angle prime lens with a fixed focus that can be used to capture visuals of both large landscapes and confined spaces.
The 20mm ultra wide-angle lens fills the space between 14mm and 24mm, so it can be used with current EOS Cinema systems for more precise shooting.
The lenses from Canon are skillfully crafted for the motion picture industry, giving you the essential equipment to confidently transform your creative concepts and narratives into reality.
Through its 12-pin electronic contacts, the RF mount significantly improves EOS-lens communication support and enables new functions.
Like EF cinema lenses, lens metadata can be read, recorded, and displayed at the destination. Compatible cameras can correct lateral chromatic aberration, peripheral illumination, and dual pixel focus guide using this data.
When shooting video with compatible cameras*, high-speed data transfer makes it possible to instantly transfer lens metadata to the camera, enabling distortion correction in accordance with lens characteristics.
*Supported cameras (as of June 2023): EOS C70, EOS R5 C (Movie Mode only)
As a defining characteristic of the Cinema Lens, the focus ring can mark numbers on both the left and right sides of the lens, allowing the distance indicator to be viewed from either side.
Changeable "ft" and "m" display units - by switching exterior components, users can toggle between feet and metres for distance marking.
