Canon CINE-SERVO 17-120mm T2.95-3.9 PL 产品宣传册
The lens is equipped with multiple blades
that make the aperture diaphragm
rounder and achieves a soft and natural
blur effect. It has also adopted an odd
number of blades so that the beams of
received light spreads without affecting
facing diffraction light each other and
creates a soft and elegant beam of light
when optimal focus is achieved.

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.

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.

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.

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

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.

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.
