WORLD’S FIRST
BUILT-IN IMAGE STABILIZER
HDTV PORTABLE LENS
The Canon HJ15ex8.5B KRSE-V portable HD zoom lens, with a built-in
Optical Image Stabilizer, is designed to maintain stable images even when the
camera is subject to jolts and vibrations. This is a compact, lightweight lens specifically
intended to produce stable HD imagery in those many shooting environments that entail
vibration and physical disturbances to the lens-camera system. The HJ15ex8.5B KRSE-V
uses Canon’s unique Vari-Angle Prism Image-Stabilizer (VAP-IS) technology to achieve a
high level of image stability, while maintaining a high optical performance to ensure
a high level of HD Image Stabilization, all the way from telephoto to wide-angle settings.
(See page 29 for the specification.)

MAIN FEATURES
▪
Preserving Full HDTV Optical Performance with incorporation of the Vari-Angle Prism
Image Stabilizer System.
▪
Powerful Image Stabilization throughout the entire zoom range.
▪
Real-time compensation for a wide range of disturbance frequencies encountered by a
camera operator who is shooting handheld while walking, running, or operating from a
motorcycle pillion, within a moving vehicle, boat, or helicopter, etc.
motorcycle pillion, within a moving vehicle, boat, or helicopter, etc.
▪
Various Stabilizing Modes - Combination of two modes from two categories is
available and each mode is simply set by changing the switches on the lens.
Select According to the
Shooting Situation
Portable mode
Compensates for motion-related disturbances
while shooting shoulder mount or handheld.
Tripod mode
Effectively compensates for disturbances
caused by unsteady platform or wind.
Select According to the
Direction of Disturbance
H+V mode
Optimizes stabilization action when disturbance
frequencies are both horizontal and vertical.
V mode
Effectively counters vertical disturbances while
operationally panning the lens-camera.
HOW THE VAP-IS (VARI-ANGLE-PRISM IMAGE STABILIZER) WORKS
Under perfect shooting conditions, light rays from a scene pass
through the lens optical system in a tightly prescribed manner.
Any vibration or jolt to the lens-camera system will deflect
those light rays and produce image unsteadiness. The
VAP-IS Technology is incorporated within the lens optical system
to intercept such light ray perturbations and correct their
deviations in real-time. The technology to do this is based upon
a flexible optical bellows that entails two flat glass elements
separated by a special liquid. This forms a sealed mini-optical
grouping within the overall lens element groupings. The bellows
expands and contracts when the lens is physically disturbed and
the very high refractive index of the liquid bends the disturbed
light rays in the opposite direction. This imparts a high degree
of real-time correction to the angle of the light rays, helping to
ensure they arrive at the image plane devoid of any unsteadiness.
