•
Precise repeatability in zoom, focus and iris control which
supports the creative digital operational functions.
•Simple integration into virtual digital studio systems
without any options.
•Dynamic zoom speed range of 0.5 sec. to over a 5
min. super slow zoom.
Moreover, Canon’s original Information Display is able
to customize the enhanced digital functions much more
easily and precisely.
Cost Effective HDTV Standard Lens
Enhanced Digital Functions
Shuttle Shot
By memorizing any two focal lengths, the Digital
Drive can automatically "shuttle" between the two
points, moving in either direction.
Frame Preset
An angle of view can be preset in either of two
memories and the lens will zoom at the highest speed
or in a preset zoom speed to the preset position by
pushing a simple button.
Speed Preset
A specific zoom speed can be preset in memory and it
is possible to repeat the zoom speed as often as you
like by pushing a simple button.

Canon’s Philosophy :
Canon has always developed new technology with four basic philosophies, "High Quality of Picture", "Ease of
Operation", "High Specification" and "Minimize Environmental Impact". Canon's HDTV lenses are, so to speak,
a compilation of our basic philosophies. Now, Canon reassembles these philosophies in the launching of a
second generation HDgc lens series.
KJ17ex7.7B
Canon’s 2nd Generation HDgc Series
The emergence of a new generation of cost-effective HDTV acquisition systems
spurred Canon to create a new category of portable lenses to better match the
price performance ratio of these cameras. This led to the introduction in 2006 of
the new HDgc lens series. Specically targeted for HD ENG, these lenses retained the
optomechanical robustness and ergonomics of the high-end HDxs lens series as well
as the same digital drive units. Canon mobilized contemporary design tools and optical
materials that facilitated a signicant cost reduction while still maintaining an impressive
overall HD imagining performance. In recognition of the continuing introduction of new improved 2/3-inch HD
acquisition systems and supported by a global experience, Canon is now introducing a second generation HDgc that
reects further design optimizations. The rst of these new lenses is the KJ17ex7.7B.
Main Features
Powerful ENG Lens for Cost Effective HD Productions
The KJ17ex7.7B is specifically designed for users whose foremost priority is a lens that delivers
a generous range of focal lengths combined with a wide field of view in a lightweight mobile
package. The lens design is a fine compromise between the demands for ruggedness and mobility
in a handheld camera system and the high imaging performance requirements for HD News and
lower budget HD productions. An important aspect of this lens is the cost optimized design
concept. Customer recommendations combined with evolving optical design strategies and
materials produced a new definition in price performance ratio for HD ENG acquisition systems that
guided the design of the new KJ17ex7.7B.
Improved Optical Performance
Compared to its predecessor KJ16ex7.7B lens, the optical performance of the KJ17ex7.7B has
been improved on a number of fronts. Utilizing special optical materials such as “Fluorite” and
“Hi-UD” (high index ultra low dispersion) glasses, most of the lens elements and optical layout
were redesigned using Canon’s advanced computer-aided techniques to achieve a new level
of optimization. Of particular significance are improvements in monochromatic and chromatic
aberrations, producing enhanced image sharpness at picture center and picture extremities. New
aspheric lens element designs have helped to further diminish geometric distortion and flare.
Improved Operability and Reduced Operator Fatigue
Coupled with innovations in optical performance, is a totally new design of the digital drive unit.
Refined by long-term market research and worldwide experience, Canon utilized the latest in 3D
CAD-CAM design to significantly improve the human tactile interface to the control of zoom, iris,
and focus. Canon’s research produced the following physical enhancements:
Reduced Physical Stress Ergonomic DesignImproved Ease of Operation
The size and curvature size have been optimized
to more comfortably fit in the palm of the operator’
s hand(a). Newly developed coatings improve the
tactile interface between the user and the drive unit
(b) together with the new Rubber Grip Support (c).
By reducing the width of the drive unit, the palm of
the camera operator's hand is positioned closer to
the optical axis, thus reducing the degree of arm
bend which in turn lessens physical stress during
prolonged shooting.
The spacing between the focus ring and drive unit
has been opened to avoid accidental interference
with the drive unit while manipulating the focus
control.
