The new Canon CINE-SERVO 50-1000mm zoom lens is an ultra-telephoto lens with superb 4K optical performance and a removable Digital Drive unit to accommodate either broadcast or cinema-style production. With the worlds longest focal length (75-1500mm with its built-in 1.5x extender) and highest (20x) magnification among Super 35mm zoom lenses, the new lens offers cinematographers new possibilities for shooting scenes in HD, 2K and 4K on single-sensor cameras.

Yuichi Ishizuka, president and COO, Canon U.S.A., Inc. said, The use of large-sensor 4K cameras is rapidly spreading beyond motion pictures and episodic television, into many new types of productions such as broadcast sports and nature documentaries. We are proud to deliver a lens with the advanced 4K optical performance, impressive focal range and operational versatility required to serve the creative needs of todays growing community of 4K and UHD image makers.

Available in either EF- or PL-mount, the Canon CINE-SERVO 50-1000mm T5.0-8.9 Ultra-Telephoto Zoom lens achieves a balance of ultra-telephoto 4K optical performance and image brightness with a compact form factor of only 15.9 inches in length (PL version) and a weight of just 14.6 pounds. This combination allows for aberration correction and high image quality extending from the centre of the image to all edges. For professional users, this lens enables close-up 4K imaging of wildlife subjects or athletes while maintaining the physical distances necessary in such shooting situations.

The lens is built to be durable and features a removable Digital Drive unit for traditional electronic field production (EFP) style operation with a convenient zoom/rocker switch, programmable zoom and focus settings, and data connections for use with broadcast-type field/studio servo-demand controls for zoom and focus. Removal of the drive unit enables cinema-style operation of the CINE-SERVO 50- 1000mm lens, including clearly engraved barrel markings, an 11-blade iris to help achieve smooth bokeh, and compatibility with lens-support rods, matte boxes, and other cinema accessories.

Lens-Camera Communication

The CINE-SERVO 50-1000mm T5.0-8.9 Ultra-Telephoto Zoom lens is compliant with industry-standard camera-to-lens communication protocols to help ensure compatibility and maximum performance with multiple brands and models of 4K, UHD and HD cameras. These standards include 12-pin serial communication, Cookes /i Technology and Canon EOS-LENS data communication technology.

Broadcast-Style Operation

The new lens integrates advanced broadcast-style operability features including servo control of focus, zoom, and iris settings via the lens removable Digital Drive unit. The unit also integrates a high-precision, high-resolution 16-bit microprocessor encoder linked to a convenient zoom/rocker switch which provides immediate start-up. This encoder enables camera operators to smoothly zoom at a variety of speeds, from a very fast 1.5 seconds to a very slow 180 seconds; from full-wide to full-telephoto.

Additionally, the encoder is capable of transmitting accurate analogue and serial data for zoom, focus and iris settings through the Drive units 20-pin connector, allowing for this lens to be incorporated into most existing virtual imaging systems.

Operators can also manually control focus and iris settings from the drive unit or use it to program focus, zoom position/speed, and iris settings if desired, allowing for precise, repeatable lens operation. A small LCD display on the drive unit displays current settings for operators. Focus can also be adjusted manually by rotating a knurled rubber collar on the lens. Combining both broadcast operability and the accuracy required by cinematographers, the lens features a 180-degree focus rotation angle. In addition to its three 20-pin connectors, the drive unit also has a broadcast- standard 12-pin power connection for remote-control operation. The lens utilises 700mA of power.

Cinema-Style Operation

With its Digital Drive unit/hand grip removed, the CINE-SERVO 50-1000mm T5.0-8.9 Ultra-telephoto Zoom lens provides digital filmmakers with the advantages of its 1500mm focal length (with 1.5x extender) and 4K optical performance. Facilitating cinema-style use, lens-barrel markings are clearly engraved in both feet and meters on both sides of the barrel, and focus indicators on the front side of the lens are marked on an inclined surface to make them easy to see from the back of the camera. Additionally, luminous paint is used for the scale display on one side of the barrel to help make the markings visually identifiable in the dark. Both 0.8 type and 0.5 type gear module focus accessories can be used, and gear positions support the use of a follow focus and all other standard electronic accessories. With a 31.4mm image circle, this lens covers industry standard Super-35mm format sensors.

A red alumite identity colour is used for the lens mount area to indicate conformance with Canon Cinema EOS optical technologys features such as support for EOS-LENS data communication. A structure enabling the lens EF mount to be replaced with a PL mount, or vice versa (electrical system included), is also incorporated. This conversion upgrade can be provided at authorized Canon service centres. The EF and PL versions of the lens are designated CN20x50 IAS H/E1 and CN20x50 IAS H/P1, respectively.
