7.6B
Recent years have witnessed expansions in both HD production and the range of
program genres. Within this environment the worldwide popularity of the HJ22ex7.6B
lens as a flexible multipurpose lens exhibiting high optical performance and ease of
operation has grown significantly. The combination of a generous 22x zoom ratio and
a wide 7.6mm field of view meets numerous challenging production applications that
include dramas, documentaries, sports, news etc.
A newly developed digital drive unit has further streamlined the lens ergonomics to
further empower camera operator shooting flexibility.
The new drive unit will be identified with an “A” at the end of the model name – such as
IRSE A or IASE A.

Main Features
High Specification in Compact Size
The focal range of 7.6mm to 167mm can be further extend to 334mm using
the 2x range extender included in the lens. This highly flexible lens has been
reduced in length to 221.5mm and in weight to 1.81 kg (IRSE A type) producing a
remarkably compact package that supports a broad range of productions.
Tight Control Over Optical Aberrations
Close attention to managing a reduction in a variety of optical aberrations while
also adopting an innovative new focusing system has produced an overall
performance improvement over the predecessor model that benefits both HD
ENG and general HD production.
High Optical Performance
Evolving design techniques, advanced optical materials and optical coatings, and
continuing refinements to manufacturing processes have collectively contributed
to the HJ22ex7.6B lens having very high optical performance and extended
operational capabilities. Specifically these include a lowering of longitudinal
chromatic aberration at the longer focal lengths, and curtailment of spherical and
comatic aberrations. Adoption of new optical materials also afforded a reduction
in curvature of field. The lens focusing system has also been improved over the
conventional 2-group inner focus in terms of an improved resolution and contrast
at the picture extremities especially at the telephoto side of the focal range.
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 changed to avoid accidental interference
with the drive unit while manipulating the focus
control.
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).
Reduced Physical Stress
Enhanced Digital Drive Unit
The incorporation of miniature 16-bit, high resolution
Rotary Encoder Devices into the new enhanced digital
drive unit, has extended the features of the HJ14x to
include:
• Precision control of all lens operations
• Precise digital repeatability of zoom, focus and iris
control that support innovative image creation
• Simple and direct digital integration into virtual studio
systems
• Precision zoom control over a total speed range of 0.5
sec. to more than 5 min.
Moreover, Canon's unique Information Display provides
easy, precise customization of the enhanced digital
functions.
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.

Improved Operability & 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 mobilized the latest in 3D CAD-CAM design to significantly improve
the human tactile interface to the control of zoom, iris, and focus. Here are some results of Canon's research:
