CN20x 50 IAS H E1/P1: a class-leading

ultra-telephoto 4K
cine-servo zoom

Combining decades of experience in the design of market-leading broadcast lenses with technology derived from high-performance cine zooms, the CN20x 50 IAS H E1/P1 responds to the growing popularity of large sensor video cameras in broadcast production. With an outstanding focal length of 50-1000mm, expandable to 75-1500mm via a built-in 1.5x extender, the lens is tailor-made for camera operators in both traditional broadcast and movie environments.

Who is it for?

The CN20x 50 IAS H E1/P1 is a superb lens that’s designed for broadcast use with Super35mm cameras – whether HD, UHD or 4K. It has unprecedented quality, versatility and usability and features a completely removable updated servo drive unit that enables its use in broadcast-style shooting environments where typical cine lenses are usually impractical. This lens offers a unique combination of broadcast operability and incredible accuracy, thus meeting the growing user-demand for Ultra High Definition (UHD) resolution sports and nature television production.

It is highly flexible to meet the huge, and highly unpredictable, demands of sports productions that typically require extremely high resolution for close-to-the-action stadium work whilst, for nature TV productions, operators work in hostile and sensitive conditions that often necessitate shooting from extremely long distances. In both environments, operators require fast, reactive positional changes, shooting flexibility and nimble hardware that allow them to respond to changes in the scene.

The CN20x 50 IAS H E1/P1 is perfectly suited to tripod-mounted use during studio or outside broadcasts, too. Zoom, focus and iris can all be controlled using Canon’s existing zoom and focus demands, providing precise and convenient control over vital image parameters without the operator touching the lens. Virtual studio use is also supported thanks to a sophisticated 16-bit encoder output.

Using Canon’s incredibly rich heritage of optical expertise, this servo-powered lens – designed for Super35mm cameras – offers outstanding 4K image quality from image centre to image edge. Available in both EF-mount and PL-mount versions it incorporates an 11-blade diaphragm to deliver softer, more attractive out-of-focus areas than 9 or 6 blade equivalents.


An unrivalled 20x zoom together with an in-built 1.5x extender deliver a class-leading focal length spanning from 50mm right up to 1500mm. Carriable and lightweight it is the ideal field lens for sport events and wildlife applications with high optical performance across the entire zoom range. It is also both weatherproof and shockproof for excellent durability in any shooting environment.


The CN20x50 IAS H E1/P1 employs a servo drive unit, enabling use in broadcast-style shooting environments where cine lenses are impractical. The compact design weighs only around 6.6kg and offers a familiar and intuitive operating experience. It’s ideal for tripod-based and virtual studio use. The focus ring rotation of 180o beautifully balances the accuracy required for 4K imaging with the speed needed for broadcast use.


The lens is also ideal for cinema-style applications. The servo drive unit is easily removed for operation as a traditional cine lens – and just as easily re-installed. No adjustment of gear positions is required, thus enabling a fluid, versatile shooting style that was previously unavailable with large sensor cameras.

The lens is fully compatible with industry-standard accessories and matte boxes as well as 0.8- and 0.5-type gear module accessories such as follow focus units. The front diameter of the lens is Φ136mm and it’s also colour-matched, for easy integration with results from the Canon EF Cinema lens range.


For added versatility the CN20x50 IAS H E1/P1 supports multiple lens communication methods. Canon’s EF-mount version supports lens metadata and other functions. A 12-pin serial connection provides a compatible interface for broadcast environments. Cooke /i Technology is supported in the PL-mount variant, allowing capture of lens data by cameras often used in movie production environments.
