CN7x17 KAS S E1

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
