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 
Stabilizer (Shift-IS) to help overcome image shaking at telephoto focal length. Now 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, 
HJ40x10B IASD-V, and HJ40x14B IASD-V.
SPECIAL OPTICAL ELEMENTS AND THE SUBERB OPTICAL 
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
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.
Then, Canon introduced one of its highest achievements, 
the DIGISUPER 86xs and DIGISUPER 86 TELE xs,  
the world’s first lens in the 80x range. This lens has  
reduced the problem of image shake that would  
have limited the 86x zoom ratio with its unique  
built-in “Optical Image Stabilizer.”
Amazingly, the 86x exhibits improved specifications  
and employs the “Optical Image Stabilizer” in a package 
the same size and weight as previous lenses. 
In 2002, Canon proudly introduced the world’s first  
triple digit zoom lens, the DIGISUPER 100, with  
“Optical Image Stabilizer” and a 100x zoom ratio. 
Canon’s goal is to pursue its philosophy with unique  
ideas and advanced technologies thus allowing Canon to 
contribute to the expansion of an ever-changing industry.

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.
