Canon CINE-SERVO 17-120 Brochure

Canon’s proprietary optical technology that realizes high
image quality EF cinema lenses*

Aspherical lens manufacturing technology

Spherical lens refracts more in the periphery portions than in the center.
For that reason, it is impossible to collect a beam of light at the optimal
one point. This is called spherical aberration, and this aberration can be
corrected by combining multiple lenses. On the other hands, the
aspherical lens can collect the light that passes through both the center
portion of the lens and the periphery portion of the lens at one point. The
performance obtained by using several spherical lenses can be achieved
using a single aspheric lens. Therefore, the number of lenses in the entire
lens configuration can be reduced. This technology contributes to a
reduction in the size and weight of the lenses and at the same time
makes it possible to produce sharp images owing to its outstanding
optical performance. Canon produces high-performance aspherical lenses
by means of advanced manufacturing technologies such as aspherical
surface grinding and glass molding processes.

Reducing changes in angle of view to enable stable framing

The CN7x17 KAS S has adopted the inner-focus-type lens formed by a three-lens group, which is a highly proven configuration for
broadcast and cinema applications. The lens reduces changes in angle of view that are caused by focusing.

Canon's surperb optical material technology

[Fluorite]

In theory, chromatic aberration cannot be completely

eliminated in standard optical glass, and a slight
chromatic aberration always remains. A material
called fluorite (CaF2) can be used to resolve this
problem in optical glass and enables ideal chromatic
aberration correction. Fluorite has been known to
have an anomalous dispersion characteristic (which
optical glasses do not have), which is effective in
eliminating chromatic aberration. Fluorite lenses have
been used in a number of Canon lenses and
effectively correct the chromatic aberration.

Rough uorite

Fluorite lenses

[UD and Hi-UD glasses]

The development of glass materials with an anomalous dispersion
characteristic similar to fluorite has been progressing recently. These efforts
have produced Ultra-low Dispersion (UD) glass. Since UD glass has low
dispersion as well as an anomalous dispersion characteristic, effects similar
to those of fluorite can be achieved by selecting the proper combination.
Furthermore, Hi-UD glass offers high refraction in addition to low and
anomalous dispersion characteristics of UD glass, which enables spherical
aberration correction as well as chromatic aberration. Hi-UD glass is used
for Canon lenses and effectively functions to reduce aberration fluctuation
caused by focusing and zooming, in addition to the chromatic aberration
that occurs on the telephoto side.

Imaging Excellence with Optimized Operational Performance

CN7×17KASS

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.

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-per formance 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.

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.

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.

Focus indicators are marked
on the inclined surface.

The focus ring markings are
indicated both in feet and
metric units(ft/m).

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.

endure in severe operating environments for broadcast applications.

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.
