Canon Cine-Servo CN7x17 KAS S/P1 Specifications

CN 7 17 KAS S

New Era, New Concept

Signiﬁcant changes are taking place at video production sites around the world today. As cinema equipment goes digital, a video creation

process that takes full advantage of the characteristics of the large-format cameras (such as shallow depth of ﬁeld, high sensitivity, low

noise, and wide dynamic range), that have been used for conventional cinema applications, is becoming more widespread for broadcast

applications such as TV dramas, documentary programs and promotional videos. In response, there is a growing demand for lenses that

can achieve excellent optical performance, as well as operability and applicability suitable for shooting when carrying a large-format

camera on one shoulder and using broadcast lens standard controllers.

Canon is introducing a new concept lens called CINE-SERVO CN7x17 KAS S to the market. The CN7x17 KAS S was developed by

integrating the best aspects of the technologies that the company has acquired through the development of broadcast zoom lenses and EF

Cinema Lenses over the years and by further evolving those technologies.

The CN7x17 KAS S offers stunning 4K camera-compatible optical performance and is compact and lightweight, which allows the camera

operator to shoot with the camera carried on one shoulder. It is also an extremely innovative lens that features a high magniﬁcation of 7x

and covers a very broad focal length range of 17mm to 120mm. In addition, the lens can be operated through broadcast lens standard

controllers and also used as a cinema lens with full manual operation by detaching the drive unit from the lens.

Canon intends to meet the requirements of broadcast lens users, cinema lens users and a wide range of users involved in video

production, by delivering the inﬁnite possibilities of high-grade 4K image expression and comfortable and easy operation.

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).

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.

Iris close function

The lens can close the iris completely, which is necessary to calibrate black balance.

Operability and functions ideal for broadcast

lens users

The lens o ers 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.

f=120mm

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

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.

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.

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.

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 rmware 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 e ect. It has also adopted an odd

number of blades so that the beams of

received light spreads without a ecting

facing di raction light each other and

creates a soft and elegant beam of light

when optimal focus is achieved.
