Canon CN-E 30-300mm T2.95-3.7 L S Cinema Zoom Lens EF Mount

The Canon CN-E 30-300mm T2.95-3.7 L S is a cinema zoom lens built for professional filmmaking applications. Covering a focal length range of 30mm to 300mm, it offers a 10x zoom range that makes it a versatile tool for productions requiring flexibility across wide-to-telephoto compositions without changing lenses. The lens is designed for the Canon EF mount and is optimized for the cinema and video camera system category.

With a maximum aperture of T2.95 at the wide end, it provides solid light-gathering capability for cinematic work, with the aperture extending to T3.7 at 300mm. The lens is formatted for full-frame coverage and is a manual focus design, which is standard practice in cinema lens sets where precise, repeatable focus pulls are performed by dedicated focus pullers using follow focus systems. At 3,000 grams, this is a substantial piece of glass suited to professional rigs rather than lightweight handheld setups.

No image stabilization is included, which is typical for dedicated cinema lenses used on stabilized rigs or tripod-mounted configurations. The T-stop rating system used here, rather than f-stop, provides cinematographers with accurate transmission values that account for light loss through the optical elements — a meaningful distinction for matching exposure across a lens set.
