4K camera-compatible stunning optical performance
The CN7x17 KAS S features high resolution from the center to the perimeter of the image and delivers a high-grade, 4K camera-compatible optical performance throughout the zoom range. The lens makes use of wide-diameter aspherical lenses and other optical material technologies, incorporating with cutting-edge simulation technology to achieve optimal optical configuration and correct various aberrations. Furthermore, the latest coating technology is used to minimize the occurrence of ghosting and flare.
High magnification covering a broad focal length range from wide angle to long focus
The CN7x17 KAS S offers outstanding 4K camera-compatible optical performance and at the same time covers a very broad focal length range of 17mm at the widest angle to 120mm telephoto. With just this lens, you can expand your creative possibilities for image expression.
Imaging Excellence with Optimized Operational Performance
Shooting with a camera carried on shoulder
The lens is compact and lightweight, and still can be used with large-format cameras. Since the lens uses a new drive unit and lens barrel with the same size as that of broadcast ENG lenses, it inherits the holding feel of the broadcast lenses (where the distance from the optical axis of the lens to the palm is close), highly preferred by broadcast camera users. Therefore, the lens provides stability in camerawork and does not cause user fatigue even when the camera is carried on one shoulder.
Support for standard broadcast lens controllers
The lens enables operation using broadcast lens standard controllers (such as the ZSD-300D and FPD-400D).
Outstanding servo performance
The lens features a high-speed zoom, ensuring that critical moments are never missed. It provides wide-ranging drive speeds and remarkable reproducibility from high to slow speeds, which allows operation just as required by a camera operator.
Immediate system start-up
The drive unit has a high-performance encoder so that the lens requires no initialization. Since the encoder does not require the initialization operation when the lens is powered on, the system can be started immediately.
Support for virtual image data output
The drive unit has three 20-pin connectors and a high-performance encoder which can output 16-bit precision virtual image signals that produce more stunning virtual image.
Standard broadcast camera interface 12-pin connection cable
The lens is equipped with a 12-pin connection cable, which is the standard interface for broadcast lenses and can be used to supply power to the drive unit and to perform iris remote control etc. (Compatible cameras with 12-pin serial communication.) A system with a camera adapter may require an extension cable EC-120/400.
Enabled a stable framing by suppressing change of angle of view
The CN7x17 KAS S has adopted the three-group inner focus system (a highly popular system for broadcast lenses and EF cinema lenses) that reduces changes in the angle of view during focusing to assure stable framing at all times.
Iris close function
The lens can close the iris completely, which is necessary to calibrate black balance.
Flange-back adjustment mechanism
The lens enables ange-back adjustment with an operation as easy as that of broadcast ENG lenses
Macro function
The lens enables macro shooting with an operation as easy as that of broadcast ENG lenses.
Operability and functions ideal for broadcast lens users
The lens oers the equivalent servo operation feel as broadcast portable lenses for all focus, zoom, and iris controls. The focus ring is provided with a knurled rubber for superior operability, which allows the equivalent manual operation feel as broadcast portable lenses.
Robustness and durability
The lens features an optimal housing structure made by combining the know-how acquired through the development of Canon broadcast lenses with the latest simulation technologies. The lens provides a robustness and durability that can endure in severe operating environments for broadcast applications.
Cinema-style shooting
When the drive unit is detached from the lens, the lens can be used as a cinema-style full manual zoom lens.
Easier-to-read ring markings
- The lens provides focus ring markings on angled surfaces on the lens barrel, which makes it easy to read the focus settings from behind the camera. •Each ring marking is indicated on both sides of the lens to facilitate operation when the cinema camera users use the lens at a movie shooting location. The ring markings indicated on one side of the barrel are coated with luminous paint so that they can be easily read even in the dark.
- The focus ring markings are indicated both in feet and metric units (ft/m), making it unnecessary to replace the focus ring in order to switch from feet to metric and vice versa.
Easy-to-understand focal length indications
The focal length is indicated on the side of the lens front barrel. The lens adopts customary “focal length indications” normally used by cinema camera users.
Support for cinema industry standard accessories
The lens can be used with standard accessories in the cinema industry, such as a matte box, follow focus gear systems, and electronically operated controllers. The focus ring is equipped with 0.8mm and 0.5mm gear modules and the zoom ring is equipped with a 0.5mm gear module, and these make it possible to use the lens with standard accessories in the cinema industry. (The iris ring is equipped with a 0.4mm gear module.)
15mm- and 19mm-diameter rod systems
The lens is equipped with a support holder for cinema lens support rods that can be used with 15mm- and 19mm-diameter rod systems. An extension shaft (included in the product) is required to use the 19mm-diameter rod system.
Compliant with wide-ranging communication standards and with a lens-to-camera communication function for added convenience
- CN7x17 KAS S EF-mount lens communicates via an electrical contact when using with a cameras of CINEMA EOS SYSTEM, which enables effective handling of shooting conditions through storing lens data such as zoom position when that picture was shot, as well as other EF Cinema Lens series (Compact Zoom Lens and Prime Lens series). The EF-mount lens will enable to automatically correct pictures by upgrading firmware of the camera.
- CN7x17 KAS S PL-mount lens is compatible with Cooke’s /i Technology, which enables transmission of focus, zoom, and iris position data as well as the lens model name so that the camera and editing equipment can display and store the lens information, which further enhances the convenience factor.
- Furthermore, the lens is provided with the standard 12-pin interface connector that is used in the broadcast industry. Therefore, the lens can perform the same type of communications as conventional broadcast portable lenses, such as transmission of focus, zoom, and iris position data as well as remote-controlled operation of the iris.
11-blade aperture diaphragm
The lens is equipped with multiple blades that make the aperture diaphragm rounder and achieves a soft and natural blur eect. It has also adopted an odd number of blades so that the beams of received light spreads without aecting facing diraction light each other and creates a soft and elegant beam of light when optimal focus is achieved.
