Expand your Canon cine-style lens choices with the full-frame CN-E 20-50mm T2.4 LF Cinema EOS Flex Zoom Lens. This PL mount lens is color matched to the rest of the EOS cine line, featuring a warm look with natural skin tones and accurate color rendition. The 20-50mm Flex Zoom and its 45-135mm counterpart both boast a fast T2.4 maximum aperture across their entire focal ranges, enabling low-light capture with the ease of a zoom lens.

Interchangeable EF and PL lens mounts make it easy to use the Flex zooms with a variety of cine-style cameras. Coated glass elements reduce chromatic aberration and block flares and ghosting, making this 2.5x zoom ideal for 4K to 8K cine-style HDR capture. An 11-blade iris produces soft, cinematic bokeh, and consistent .08 MOD gear placement and front diameter size suit the Flex zooms for use with industry-standard matte boxes and accessories. This PL-mount lens features Cooke i/ metadata display and pass-through, enabling you to record information that is crucial to FX and post-production conforming.
