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.
  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.
