Description — Canon 20mm T1.5 LF
The Canon CN-E 20mm T1.5 LF Cinema Prime Lens is engineered for professional cinema production, offering a 20mm fixed wide-angle focal length on the Canon EF mount with full frame sensor coverage. The T1.5 maximum aperture makes this a strong performer in low-light conditions and provides the ability to work with shallow depth of field when the creative brief demands it. As a manual focus prime with no autofocus capability, it is designed to integrate into cinema rigs with follow focus systems for precise, repeatable focus pulls.
There is no image stabilization, so use on a stabilized platform or rig is recommended for smooth motion work. Weighing 1.2kg, the lens has the solid build expected of a dedicated cinema prime. No filter thread size is provided in the specifications, so users requiring filtration should plan for a matte box or other filter solution.
This lens is purpose-built for the demands of serious cinema production workflows.
