Canon’s Compact-Servo Lens family welcomes its second addition with the 70-200mm T4.4 EF lens. The Compact-Servo 70-200mm allows for control of the zoom, focus, and iris using an externally integrated servo unit. This compact and versatile lens is compatible with industry standard broadcast lens controllers including Canon’s own ZSG-C10 Grip Unit.
Three levels of Image Stabilization and incorporated autofocus functions set the COMPACT-SERVO 70–200mm T4.4 EF lens apart from traditional Super 35mm Cinema lenses. This lens is parfocal in both manual and autofocus modes using a compensating lens group that moves to maintain precise focus. With at 2.8x zoom magnification, the 70-200 is also able to maintain a consistent aperture of T4.4 throughout its range.
Compact-Servo CE-E70-200mm T4.4 Features:
4K Cinema Lens
Manual & Autofocus Modes
Indespensible 70-200mm Range
Weighing in at 2.76lbs., and with a compact size of only 7.2in., you’ll be hard-pressed to find a more portable 4K lens in this zoom range. The Compcat-Servo 70-200mm also features a 130° smooth rotating focus ring that compliments nicely its 9-blade iris which creates a rounded aperture so out-of-focus highlights appear circular instead of starburst.

Canon has designed the COMPACT-SERVO 70–200mm T4.4 EF lens specifically to work with compatible Cinema EOS cameras, resulting in a complete kit that adds enhanced functionality. Integrated autofocus, smooth image stabilization, connected control and metadata information as well as lateral chromatic aberration correction are all available when using the lens on compatible Cinema EOS cameras.
Autofocus Function. Canon cameras feature advanced autofocus functions. The 70–200mm T4.4 EF lens is designed to work with select Cinema EOS cameras to offer fast and accurate autofocus control. All autofocus controls can be switched off to allow manual focus.
Continuous AF. Different Canon cameras offer various types of continuous autofocus functionality. The fast servo response of the 70–200mm T4.4 EF lens allows for continuous smooth autofocus as with select Cinema EOS cameras. All electrical control of the lens is done directly through the EF-mount.
One-Shot AF. One-Shot Autofocus is a quick reference setting of focus using the autofocus servo system. The camera sets focus of the image the moment the AF button is pushed. Once the control is released, the focus will remain set to that distance. This temporary engagement of autofocus can be useful for selective artistic focus control.
Focus Guide. Select Cinema EOS cameras can use autofocus technology even with the servo control on the 70–200mm T4.4 EF lens disabled. Even with the lens in manual mode, the camera will detect its focus setting and can indicate suggestions in the viewfinder on adjustments for focus in the image.
Image Stabilization (IS). The 70–200mm T4.4 EF lens is a medium to telephoto zoom. The longer the focal length the more sensitive it is to any shake in the movement. The lens offers three levels of Image Stabilization, including the standard mode for handheld operation, a maximum mode for high-frequency movement and a smooth mode intended for tripod-based operating. The IS function can also be switched off entirely.
EF Communication Functions. There are a host of functions designed to help maximize the integration of the 70–200mm T4.4 EF lens with select Cinema EOS cameras. Integrated autofocus, smooth image stabilization, connected control and metadata information, and lateral chromatic aberration correction are all included when using the lens on compatible Canon Cinema cameras.
Remote Control of Zoom, Focus and Iris via Camera. Select Cinema EOS cameras can power and control the servo drive of the 70–200mm T4.4 EF lens by electrical connection through the EF-mount. A zoom control on the camera body can alter focal length, the autofocus modes of the camera can directly engage the lens focus servo, and the auto exposure camera functions can operate the lens iris to adjust light transmission. Integrating these controls allows easier single-person camera operation, and the 70–200mm T4.4 EF lens can be switched into a partial or fully manual mode if desired.
REC Start/Stop from ZSG-C10 Zoom Servo Grip. Through the EF-mount, the ZSG-C10 Zoom Servo Grip that mounts to the 70–200mm T4.4 EF lens can control record triggering on select Cinema EOS cameras. The optional handgrip also features a zoom servo rocker control and an autofocus engage button.
Peripheral Illumination Correction. Select Cinema EOS cameras can communicate with the 70–200mm T4.4 EF lens to profile its illumination characteristics, and electronically compensate for image brightness dimming in the edges of the frame.
Lateral Chromatic Aberration Correction. The 70–200mm T4.4 EF lens was designed to help minimize lateral chromatic aberration for Super 35mm sensors. Any remaining minimal lateral chromatic aberration is mathematically mapped so that the lens can communicate with select Cinema EOS cameras, which then in turn electronically correct for the artifact.
Lens Meta Data Record. The 70–200mm T4.4 EF lens sends reference information constantly to the camera, noting precise settings for focus, iris and zoom. Data is also transmitted about the lens model itself, and on select Cinema EOS cameras. This information can be recorded for use in post processing. This is useful when matching cameras as well as in VFX work. Some of this data can also be displayed in the camera viewfinder.
T Number/F Number Display Select. The 70–200mm T4.4 EF lens sends metadata information of the iris position through the EF-mount to the camera. On select Cinema EOS cameras, this information can be displayed as a T-stop, which indicates the amount of transmitted light through the aperture. It can also be displayed as an F-stop.
