Description — Canon 30-300mm T2.95-3.7 L S
The Canon CN-E 30-300mm T2.95-3.7 L S Cinema Zoom Lens on the Canon EF mount is a professional-grade cinema zoom covering 30mm to 300mm — a broad 10x focal length range that reduces the need for lens changes on demanding productions. The lens carries a T2.95 maximum aperture at the wide end, stepping to T3.7 at maximum reach, with T-stop ratings used throughout to reflect actual light transmission rather than geometric aperture. This is a manual focus lens designed for the cinema and video camera system workflow, where focus control is handled via follow focus rigs and dedicated crew.
The lens is built to a full-frame image format specification and carries a Canon EF mount. Weighing 3,000 grams, it is a substantial cinema optic intended for rigged, supported production use. No image stabilization is present, consistent with its intended deployment on stabilized platforms. The combination of a wide zoom range and cinema-standard T-stop aperture rating makes this lens a practical choice for productions seeking flexibility without sacrificing exposure accuracy.

Frequently Asked Questions — Canon 30-300mm T2.95-3.7 L S
What camera mount does the Canon CN-E 30-300mm use?+
This lens uses the Canon EF mount. It is designed for use with cinema and video camera systems that accept the Canon EF mount interface.
Does this lens support autofocus?+
No. The Canon CN-E 30-300mm is a manual focus lens. This is standard for professional cinema lenses, where focus is typically controlled via a follow focus system operated by a dedicated focus puller.
What does T2.95 mean and how does it differ from an f-stop rating?+
T2.95 is a T-stop rating, which measures actual light transmission through the lens rather than just the aperture diameter ratio used in f-stop calculations. T-stops are preferred in cinema because they give more accurate exposure matching across different lenses in a set.
How heavy is the Canon CN-E 30-300mm?+
The lens weighs 3,000 grams. This is a substantial cinema zoom that is best suited for tripod, shoulder rig, or other supported shooting configurations rather than lightweight handheld use.
Does the lens include image stabilization?+
No, image stabilization is not included on this lens. Cinema productions using this lens would typically rely on external stabilization solutions such as tripods, gimbals, or motion control rigs.
What is the full focal length range of this lens?+
The lens covers a focal length range of 30mm to 300mm, providing a 10x zoom range. It is classified as a telephoto zoom and is formatted for full-frame image circle coverage.
