Cost Effective HDTV Telephoto 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 specifi c 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 Specifi cation" 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.
KJ22ex7.6B
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. Specifically 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 significant 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 end-user experiences, Canon is now introducing a second
generation HDgc that reflects further design optimizations. Adding to the Standard KJ17ex7.7B, meet the new
Telephoto KJ22ex7.6B.
Main Features
Multi-purpose Telephoto Lens for Cost Effective HD Productions
The new KJ22ex7.6B is a telephoto lens covering a generous range of focal lengths while also
providing a modest wide-angle of almost 65 degrees in the 16:9 HD image format. This provides
a very fl exible image framing range especially for outdoor applications. The central design criteria
for this new lens sought an excellent balance between size, weight, and HD optical performance
intended for HD News and many HD production applications. Customer recommendations based
upon experiences with our fi rst generation HDgc telephoto lens combined with the harnessing of
new optical design strategies and new advanced optical materials to produce an excellent overall
price performance ratio for the new KJ22ex7.6B.
Improved Optical Performance
The optical performance of the KJ22ex7.6B has been improved on a number of fronts compared
to its predecessor KJ21ex7.6B. The new lens deploys Large Diameter Aspherical lens elements
that contribute to a better control of comatic aberration, geometric distortion, and corner
resolution. Curvature of field and chromatic aberrations have been reduced by use of special
optical materials that include Fluorite and Hi-UD glasses. Computer optimization of both the optical
and optomechanical designs contributed to achieving a high-performing telephoto lens within a
compact and lightweight body.
Improved Operability and Reduced Operator Fatigue
Coupled with innovations in optical performance, is a totally new design of the digital drive unit.
Refi ned by long-term market research and worldwide experience, Canon utilized the latest in 3D
CAD-CAM design to signifi cantly 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 Design
Improved Ease of Operation
The size and curvature size have been optimized
to more comfortably fi t 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.
