OPTICAL IMAGE STABILIZER
EMPLOYMENT OF VARI-ANGLE PRISM IMAGE STABILIZER (VAP-IS)
Canon introduced an important new HD production portable lens, the
HJ15ex8.5B KRSE-V. This lens incorporates an innovation intended
to significantly enhance HD motion imaging on location shoots of
many forms. The lens has a built-in optical image stabilization system
that employs Canon’s patented Vari-Angle Prism Image Stabilizer
(VAP-IS). Canon’s IS technology has been dramatically improved since it’s earlier deployment
in a standard definition lens, and produces highly stable HD imagery when the lens-camera
system is subjected to a wide range of disturbance frequencies encountered in many shooting
environments. These can range from very low frequencies in handheld or shoulder-mount
shooting by a walking or running camera operator, to higher vibration frequencies associated
with operation on motorbikes, moving vehicles, and helicopters. Various stabilization modes
of operation are selectable to address diverse shooting operations.

OPTICAL SHIFT IMAGE STABILIZER (SHIFT-IS)
The history of field lenses is a history of
zoom ratio/focal length extension. Many in the
industry thought it would be impossible to push the
envelope any further. The telephoto focal lengths of
the lens got so long that even the slightest amount of
wind or operator movement would cause image shake
and viewing the picture became intolerable. This was
before Canon announced the incredible magnification
DIGISUPER 86xs zoom lens. Canon, renowned for
its optical image stabilization technologies,
developed another new stabilization solution for the
broadcast field lens, a built-in Optical Shift Image
zoom ratio/focal length extension. Many in the

Shift-IS is employed in the UHD DIGISUPER 90, UHD DIGISUPER 86, DIGISUPER 100,
DIGISUPER 100AF, DIGISUPER 95 TELE, DIGISUPER 95, DIGISUPER 86AF, DIGISUPER 80,

SPECIAL OPTICAL ELEMENTS AND THE SUBERB OPTICAL
LAYOUT (X-ELEMENT AND THE POWER OPTICAL SYSTEM)
LAYOUT (X-ELEMENT AND THE POWER OPTICAL SYSTEM)
Canon has always made an effort to research special elements since its
beginnings in this industry with the goal of minimizing chromatic aberration.
These efforts have included an artificially re-crystalized “Fluorite,”
with outstanding dispersion characteristics and the developed
“Hi-UD” (high index ultra low dispersion) glass. Canon has succeeded in
the practical use of special elements along with advanced design techniques
like “separate achromatism.” Canon TV zoom lenses carry a “Green Ring”
on the focus barrel, a symbol of its high quality.

Canon developed an optical design technology known as the “Power Optical System,” whose heart
is the “X-Element.” By using the “X-Element” to its maximum power in the specially designed optical
layout, higher specifications and quality can be achieved in smaller and lighter lenses. The lenses
designed using the “Power Optical System” are known as the “XS-series.”

CANON LENS EVOLUTION: LONGER, WIDER AND MORE
SENSITIVE LENSES
SENSITIVE LENSES
Canon previously released several lenses in succession:
the J13x9B II in the early 80’s, which became the world’s
standard ENG/EFP lens; the J18x9B in 1984; and in 1985,
the J8x6B. These lenses became the first example of
todays standard series of ENG/EFP lenses composed
of a Telephoto, Standard, and Wide zoom lens. With the
current HDTV series, Canon has developed longer, wider,
and more sensitive lenses that are approximately the
same size and weight as the very first series with vastly
improved specifications.

In Studio/Field category lenses, Canon developed the
first 40x high zoom ratio lens in 1982 and since then
has cleared hurdle after hurdle, breaking new ground
by introducing the world’s first 50x and 70x lenses.

HOW THE OPTICAL SHIFT IMAGE STABILIZER (SHIFT-IS) WORKS
When the lens moves, the light rays from the subject are bent relative to the optical
axis, resulting in an unsteady image because the light rays are deflected. By shifting
the IS lens group on a plane perpendicular to the optical axis to counter the degree of
image shake, the light rays reaching the image plane can be steadied. Since image shake
occurs in both horizontal and vertical directions, two shake-detecting sensors for yaw
and pitch detect the angle and speed of movement. This information is then sent to a
high-speed 32-bit microcomputer, which converts the information into drive signals for
the IS lens group. Then the actuator moves the IS lens group horizontally and vertically
thus counteracting the image shake and maintaining the stable picture. The Shift-IS
component is located within the lens group and is most effective for lower frequency
movements caused by platform vibration or wind effect without increasing the overall
size and weight of the master lens.
