Product description

Broadcast-Style Shooting

Suitable for Shoulder Mounted Camera Operation
• The CN7x17KAS S 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 hand

Support for Standard Broadcast Lens Controllers
• The lens is compatible with many 20-pin zoom and focus controllers, allowing the lens to be operated comfortably in a studio tripod or pedestal configuration or remotely, say while mounted on a jib or crane. Compatible controllers include the Canon FPD-400D focus control and the Canon ZSD-300D zoom control

Variable Speed Servo
• High 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 0.5 to 300 seconds

Immediate System Startup
• The 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 up

Supports Virtual Image Data Output
• Via three 20-pin connectors below the servo it is possible to connect an external system to collect 16-bit virtual image data

Standard Broadcast 12-Pin Camera Interface Cable
• The lens features the same 12-pin camera interface for power and serial data as found on regular Canon broadcast lenses

Broadcast Lens-Style Focus Ring
• In addition to servo zoom, focus, and iris another ENG-derived feature is the knurled focus ring, which is limited to a 180° rotation

Angle of View Shift Suppression
• The lens features a three-group inner focus system that is designed to minimize angle of view shift (breathing) that occurs when focusing the lens to ensure stable framing even during rack focus

Flange-Back Adjustment
• The 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 distances

Macro Function
• The zoom ring features a broadcast lens-style release allowing the lens to quickly set to macro or back again

Fully Closing Iris
• The iris may be closed fully for setting camera black balance or other calibration procedures

Cinema-Style Shooting

Detachable Drive Unit
• The motor unit housing the servo motors and zoom rocker may be removed for cinema style shooting where full manual control is preferred

Supports Super 35mm Image Sensors
• The CN7x17KAS S provides a sufficiently large image circle to cover a Super 35mm sensor

Easier-to-Read Ring Markings
• The lens incorporates the following features designed to make the markings easier to read:
  • The focus ring markings are placed on an angled surface so that they can be seen even by an operator sitting behind the camera
  • Each ring marking is printed on both sides of a lens allowing focus-pullers or camera assistants to operate the lens from various positions. Additionally, the markings on one side of the lens have a luminous coating so that they can be read even in the dark
  • The focus ring features both metric and imperial scales (meters and feet) so that you do not have to replace the lens ring to suit users accustomed to different units of measure

Support for Cinema Lens Accessories
• The 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 pitch cine standard gear ring as well as a 0.5mm Canon pitch ring, the zoom feature a 0.5mm Canon pitch, and there is also a 0.4mm pitch iris gear

Compatible with Lens Support
• Because of the weight of the lens it is often deemed helpful or necessary to support the lens using a 15mm or 19mm rod system. This lens makes that possible by allowing you to attach a lens support

Lens-to-Camera Metadata Transmission
• The lens communicates directly with Cinema EOS camera through the lens interface. This allows lens metadata such as zoom setting and iris to recorded in the camera. Note that a firmware update may be required for proper communications between the lens and the camera.
  
  In addition the lens features a standard 12-pin broadcast camera interface and can also transmit zoom, focus, and iris data to a camera or other device via this connection

11-Blade Aperture Design
• The lens features 11 aperture blades to make lens flares and orbs causes 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" effect

Lens Design

Aspherical Lens Technology
• Since 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 well

Canon Fluorite Coating
• Because 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 glass alone

UD and Hi-UD Glasses
• In addition to fluorite, the use of ultra-low dispersion (UD) glass helps reduce the chromatic aberration that is a normal part of glass lenses. Additionally Hi-UD offers high refraction in addition to low dispersion to help combat spherical as well as chromatic aberration, including the aberration fluctuation normally caused by zooming
