EFP lens with built-in image stabilizer
Canon's HJ15ex8.5B KRSE-V portable HD zoom lens provides the
solution to camera shake in the ever-demanding HDTV environment. It
also anwers the need when capturing fast moving images, especially,
in sports and drama production, and maintaining sharp focus.
The HJ15ex8.5B KRSE-V can stabilize a wide range of vibration
frequencies. Examples range from the low-frequency vibrations
encountered on a camera operator's shoulder in a jostling crowd
situation, to tripod-mounted operation on shaky platforms, to the
higher-frequency vibration that cameras are subject to when
operated inside TV news helicopters, motor vehicles, motorbikes,
and boats. The lens provides four selectable stabilization modes to
allow operators to optimize the degree of correction under diverse,
and sometimes unique, shooting conditions.
Canon's unique VAP-IS technology incorporates a novel optical
group made up of two flat glass elements joined by sealed bellows
containing a high-refractive-index liquid, selectively placed
within the lens' overall optical system. The system has been
optimized to introduce a high-degree of real-time compensation for
image instabilities.
A major advantage of Canon's unique VAP-IS system is that it
totally relieves the camera operator of any concerns with respect
to lens-camera stability, allowing full concentration on creative
image framing, focusing, and capturing imagery of the subject being
photographed.
Optical Technologies
Power Optics - combination of specialized materials, contemporary
optical design, and multilayer coatings that produce the superb
imagery.
Internal Focus - a Canon design innovation that uses a floating
optical system to better control chromatic aberrations.
Crossover Technology - switchable operation between 16:9 and 4:3
aspect ratio imagery.
Digital Technologies
New third-generation enhanced digital servo systems using
Canon-developed 16-bit optical rotary encoder devices introduce new
creativity to handheld acquisition systems. Enhanced Digital Drive
technology - encompasses a microcomputer driven servo control that
embodies position memory and user-defined digital functionality to
significantly empower the camera operator. A 16-bit rotary encoder
for aperture control reports to the associated camera Iris control
system (10-bit compatibility). Maximum Zoom speed is 0.5 seconds
and Focus is 1.5 seconds.
Mechanical Technologies
Compact digital servo drive unit is mounted to the lens at a 12.5
degree angle for comfort and balance. Magnesium alloy body for
light weight and exceptional durability.
Ecological Design
All contemporary Canon lenses avoid the use of materials and
substances potentially harmful to the environment. Lead has been
removed from all optics and other identified substances from all
components comprising the composite lens system.
