7.6B
In recent years, demand for HD production has steadily expanded to encompass a broad
variety of program genres. Under such circumstances, the HJ17ex7.6B has seen a
worldwide rise in popularity as a standard HD lens having high performance and ease of
operation.
The HJ17ex7.6B is a lens whose central design criteria were low weight and small
physical size to support greater mobility especially for HD newsgathering. It also
provides a short MOD of only 0.56m in response to a strong market request. With its high
optical imaging qualities the HJ17ex7.6B is distinguished within the HDxs lens series by a
high price performance ratio that facilitates many forms of HD program origination.
A newly developed digital drive-unit further streamlines the lens ergonomics and ease of
operation that empowers camera operator shooting flexibility.
(New drive is loaded with the lens that has ‘A’ at the end of its model name such as
‘IRSE A’, ‘IASE A’.)

Main Features
Realization of Miniaturization and Weight Reduction
The new design achieved a reduction in size that produced a total length
of 206.4mm while also reducing the weight of the lens to 1.60kg (IRSE A
type) which is crucial to more mobile shooting. Attention to the lens front
end design in the form of an optical port diameter of only 82mm and a hood
reduced in size so as to not occlude the camera operators viewing of the
scene while shooting, further contribute to the dynamic shooting capabilities of
the lens.
Short Minimum Object Distance of 0.56m
By reducing the minimum object distance to 0.56m the lens can be better utilized within confined
spaces allowing objects to be effectively imaged at short distances while operating with a wide angle
of view facilitated by the minimum 7.6mm focal length. Design improvements have lowered optical
aberrations at the wider angle and open aperture settings.
High Optical Performance
Accumulated design experiences allied with advances in optical technologies and manufacturing
techniques have contributed to a higher level of overall imaging performance in the HJ17ex7.6B
lens. In addition to providing a wider field of view some chromatic and monochromatic aberrations
have been reduced. 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 a shorter MOD and improved
resolution at the picture extremities especially over the middle to telephoto 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:
