High Zoom Magnification 7x

The new CINE-SERVO 17-120mm T2.95-3.9 lens offers a high magnification range of 7-times, coupled with an extremely versatile focal length that is continuously variable from 17mm to 120 mm. Its compact size and light weight include the same type of removable drive unit found on conventional broadcast-use ENG lenses, with ergonomics that provide a familiar feel that many ENG cameramen expect.

4K Ready

The lens offers 4K-ready optical performance for digital cameras equipped with Super35mm CMOS sensors that offer four times the image resolution of conventional HD media. The lenses' high optical performance across a wide zoom range matches that of 4K single-chip, large-format digital cameras, for both cinema and broadcast applications, with outstanding picture quality extending from the image center to the edges.

11-Blade Iris

The use of an 11-blade iris produces artistic and beautiful out-of-focus areas or "Bokeh." The 11 blades allow for attractive circular blurring in out-of-focus regions, while the use of an odd number of blades help reduce flaring of specular highlights. Additionally, the iris ring is mechanically controlled with no click stops for smooth exposure adjustments while recording.

Designed for Cinema Style and Broadcast Applications

With large-format digital cameras now being used during both cinema and broadcast/ENG shoots, videographers and operators are seeking zoom lenses that accommodate both types of production. The lens incorporates a removable drive unit that provides remote control of the focus, zoom and iris/aperture settings. Focus indicators on the front side of the lens are marked on a beveled surface, making them easier to identify from the rear of the camera especially when mounted on a shoulder. A 180-degree focus rotation angle not only fulfills the focusing accuracy required for 4K shoots, but also the operational range needed for broadcast productions.

Enhanced Servo Drive Unit

The LCD display enables users to easily access functions on the drive unit. User settings are also accessible from the drive unit. The drive unit can provide a very fast zoom speed of up to 0.5 seconds from end to end, or a very slow speed of 300 seconds. These can be changed using a toggle switch on the drive unit. The small and lightweight ergonomic drive unit can be detached when full manual use of the lens is desired, and doesn't require any alignment when re-attached to the lens. While the lens can operate independently of the drive unit, the drive unit is matched by serial number to the lens it ships with and will only function with that lens.

Compact and Lightweight

Despite being designed for large-format digital cameras, the lens is extremely compact and lightweight, with the type of shoulder-shot portability desired by broadcast-production and ENG/EFP markets.

Multiple Communication Capability with Compatible Cameras

In addition to supporting Canon's EF-mount communication protocols via camera-mount contacts, the lens features three, 20-pin ports that provide full remote control of zoom servo, focus servo and iris/aperture settings, compatible with a wide range of digital cameras, virtual data systems and remote-control protocols. They are also compatible with 12-pin lens cables used for cameras that accommodate other broadcast-compliant serial interfaces. The lens is only capable of communicating with a camera when used with the servo drive unit.

16-bit Metadata Output for Virtual Studio Systems

The lens can be connected to different types of virtual control systems via its 16-bit encoder outputs, including Canon's Digital Drive ZSD-300D zoom demand and FPD-400D focus demand. The FDJ-P01 focus demand can also be used via a 20-pin conversion cable to remotely control the iris by changing the setting from the display on the drive unit. The 16-bit, high-resolution encoders provide accurate lens data to the system to help avoid any discrepancy between the changes made in the lens settings and the virtual images.

High Durability and Ruggedness

Leveraging Canon's more than 50 years of designing broadcast lenses, the lens offers the high level of ruggedness and in-use reliability required to fulfill the exacting needs of broadcast applications, with a robust chassis construction that is weather and shock proof.

Power Supply

The lens will require an external battery to supply power for the servo drive. Please ask Canon or any authorized dealers for details.

Also Available in PL Mount

For added versatility with a range of HD and 4K digital cameras, the lens is also available with a PL mount. The mounts are interchangeable at an authorized service facility to support user needs.
