Exceptional High Optical Performance
HJ21ex7.5B No Scene will Fail to Yield to the Imaging Prowess of Canon's HD Production Lens
Main Features
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:

Specifically Designed for High-end HD Production
Focus breathing and variations in picture performance with refocusing at different
object distances have been traditional imaging challenges to high-end production
calling for high picture quality. By adopting the novel 3-group inner focus system
and setting a proper power for the front lens fixed group as well as the focus moving
group, the HJ21ex7.5B succeeded in minimizing such unwanted phenomena to an
exceedingly low level. Also the lens is designed to maintain high optical performance
across the entire 16:9 image plane, especially at the telephoto side of the focal length.
Within the standard BCTV lens lineups consisted of Wide, Standard and Telephoto
lenses, the addition of the HJ21ex7.5B establishes its own important category
supporting the special imaging requirements of the high-end HD production market.
High Imaging Performance with Special Optical Elements and
Exclusive Optical Layout
With the goal of minimizing various aberrations in order to meet the imaging
standards of high-end production, the HJ21ex7.5B adopts special optical elements
that include the artificially re-crystallized “Fluorite” featuring extraordinary dispersion
characteristics and the newly developed high index ultra low dispersion glass, “Hi-UD”
glass. These lens elements are scientifically exploited by the design of an optical
layout exclusive to this particular lens. The imaging achievement can be seen in its
high optical specifications and extraordinary performance. Featuring a broad focal
length range of 7.5mm to 158mm and a maximum relative aperture of F1.9, the lens
maintains its high optical performance throughout the entire zoom range.
Extremely small Focus Breathing
The overall demand for HD production coupled with the growing diversity of production
applications has called for an expansion in the range of HD lenses. The HJ21ex7.5B
was specifically developed to support high-end HD production where minimization of
focus breathing (unwanted alteration to angle of view that accompanies manipulation
of the focus control), high imaging performance, extended focal range and a modestly
wide angle constitute core production requirements for drama and documentary program
origination. With the addition of the new digital drive unit the shooting versatility is further
enhanced. The 7.5mm wide angle setting and the 21x zoom ratio offer a formidable
operational combination for such high-end production work.
(New drive is loaded with the lens that has ‘A’ at the end of its model name such as
‘IRSE A’, ‘IASE A’.)
