The CINE-SERVO 50-1000mm T5.0-8.9 with PL mount from Canon is designed to combine the functionality and form factor of a broadcast, ENG-style-servo zoom lens with the optical precision of a cinema zoom. The lens is designed for use on cinema cameras with Super 35 sized sensors and is suitable for 4K acquisition. With a detachable drive mechanism and support for rod attachment, it is designed to be equally at home whether being used by a solo camera operator or a full production team. The lens features a 20x optical zoom and a focal length range of 50 to 1000mm with a maximum T stop of 5.0 at the wide end. The lens features a built-in 1.5x extender providing a 75 to 1500mm zoom range, capable of supporting 4K resolution.The lens features 180� of focus rotation for precise focus pulls and is marked in both feet and meters. The detachable drive unit, can be removed and reattached with the zoom in nay position, requiring no re-calibration. It also supports motorized zoom speeds ranging from 1.5 seconds to 180 seconds to zoom throughout the entire range. The zoom control includes a mini-LCD that displays zoom, focus, and iris setting. The lens mount supports electronic signal pass through, supporting EOS lens data management functions. The built-in, 12-pin connector allows you to interface this lens with standard broadcast connectors. The 11-blade iris creates circular out of focus highlights and a natural looking Bokeh.20x Zoom RangeThe lens features a 20x zoom range of 50 to 1000mm, which is very long for a lens that supports the Super35 format. A built-in 1.5x extender allows you to increase the zoom range to 75 to 1500mm while still supporting 4K resolution.Suitable for Shoulder Mounted Camera OperationThe lens features the form factor and control layout of typical ENG lenses and is designed to be friendly for a single camera operator to control while using the camera shoulder mounted. The zoom servo is controlled by rocker with the right hand and focus and iris can be operated manually with the left handVariable Speed ServoHigh speed servo-driven zoom and iris is available for critical situations such as while filming sports or fast action. Meanwhile, slower speed settings are available for more expressive work. With this variability, the zoom duration can be set to last anywhere from 1.5 to 180 secondsImmediate System StartupThe drive unit features a high-performance encoder so that the lens requires no initialization. This means the system can be used immediately without any delay waiting for it to boot upSupports Virtual Image Data OutputVia three 20-pin connectors below the servo, it is possible to connect an external system to collect 16-bit virtual image dataStandard Broadcast 12-Pin Camera Interface CableThe lens features the same 12-pin camera interface for power and serial data as found on regular Canon broadcast lensesBroadcast Lens-Style Focus RingIn addition to servo zoom, focus, and iris, another ENG-derived feature is the knurled focus ring, which is limited to a 180� rotationFlange-Back AdjustmentThe flange back may be adjusted in the same manner as on broadcast lenses to simplify the transition between different camera systems with different flange focal distancesFully Closing IrisThe iris may be closed fully for setting camera black balance or other calibration proceduresDetachable Drive UnitThe motor unit housing the servo motors and zoom rocker may be removed for cinema style shooting where full manual control is preferredSupports Super 35mm Image SensorsThe lens provides a sufficiently large image circle to cover a Super 35mm sensorSupport for Cinema Lens AccessoriesThe lens is compatible with a wide array of accessories common in the cine industry, including matte boxes, follow focuses, and electronic and wireless controllers. The focus ring features both a 0.8mm MOD cine standard gear ring as well as a 0.5 Canon MOD ring, the zoom features a 0.5 Canon MOD, and there is also a 0.5 MOD iris gearCompatible with Lens SupportBecause of the weight of the lens, it is often deemed helpful or necessary to support the lens using a 19mm rod system. This lens makes that possible by allowing you to attach a lens supportLens-to-Camera Metadata TransmissionThe lens supports the Cooke/i Lens Camera Data protocols through contacts built into the PL-mount. This allows lens metadata such as zoom setting and iris to be recorded in the camera. Note that a firmware update may be required for proper communications between the lens and the camera.Serviceable Lens MountsThe lens mount can be swapped between PL and Canon EF only by an authorized Canon service Facility.11-Blade Aperture DesignThe lens features 11 aperture blades to make lens flares and orbs caused by the bokeh effect as close to round as possible. With fewer blades, it is often possible to see the geometric shape of the aperture. Additionally, using an odd number of blades helps prevent diffraction effects that can cause pin-points of light to produce an unwanted "staring" effectLens DesignAspherical Lens TechnologySince spherical lenses refract more in the periphery than the center, it is essentially impossible for an image to be sharp across the entire frame. Aspherical lenses, on the other hand, are able to maintain much more even focusing across the image area for more uniform focusing. In addition, it means less elements are required in the lens design helping make it not only sharper but reducing the size and weight as wellCanon Fluorite CoatingBecause glass lenses can never be totally free from chromatic aberration Canon applies a special coating, fluorite, which has an anomalous dispersion characteristic effectively reducing the aberration below what is possible with optical glass alone
