HJ14EX4.3B IRSE/IASE
Wide Angle HD Lens
After nearly a decade of advances in its world-renowned optical R&D - and ongoing dialogue with hands-on users worldwide - Canon has introduced the evolutionary next-step in high
definition imaging: the HJ14ex4.3B IRSE/IASE wide-angle portable HDTV lens. Totally new and unique in its design, the HJ14 is the product of Canon's very latest optical design tools, newly developed glass elements, and highly advanced optical coatings. In addition, the HJ14's newly developed Digital Drive unit provides improved operability and ergonomic advances for user comfort and convenient control of lens functions.
Wide, Advanced Optical Performance
Canon's HJ14 wide-angle portable HDTV lens features a minimum focal length of 4.3mm and an angular field of view of 96.3° at the wide end of the 16:9 HDTV aspect ratio. This optical performance is combined with a 14x zoom range reaching to 60mm (120mm with extender), which greatly expands creative options for the acquisition of crystal-clear, and virtually distortion-free HDTV video images.
Improved Operability, Digital Drive, and Lighter Weight
Employing free-form curves based on the shape of human hands, Canon mechanically redesigned its new Digital Drive unit to be more ergonomically friendly, making it narrower and shorter, and opening more space for manual focusing. It also features newly developed coatings and a new rubber grip support for a better tactile interface. The overall result is the enhancement of user interface and the reduction of stress and fatigue, especially during prolonged shooting. The HJ14ex4.3B also employs a smaller hood, which helps the camera operator view more of the actual scene.
HJ15EX8.5B KRSE-V
Image Stabilized EFP HDTV Lens
Canon's HJ15ex8.5B is the world's first HDTV portable 2/3- inch zoom lens with a built-in Optical Image Stabilizer. Designed to maintain stable images even when
the lens-camera is subject to jolts
and vibrations, the HJ15ex8.5B KRSE-V uses Canon's patented Vari-Angle Prism image-stabilizer (VAP-IS) technology. Its high degree of compensation is sustained all the way from telephoto to wide-angle settings. This is of particular importance considering the extreme image detail associated with HD acquisition. This unique technology greatly extends flexibilities in EFP shooting on location - all within a compact high-performance lens to weigh in at only 4.4 lbs.
Canon's Vari-Angle Prism technology entails a novel optical group made up of two flat glass elements and a sealed bellows containing a high refractive index liquid, selectively placed within the lens overall optical system. Physical perturbations to the lens, in the form of jolts or vibrations, flex the bellows proportional to the amplitude of these disturbances. The associated distortion of the liquid instantaneously alters the direction of the transmitted light rays in a manner designed to counter the incoming light ray displacements created by these disturbances. The system has been optimized to introduce a high- degree of real-time compensation for image instabilities arising from all forms of lens-camera operational unsteadiness.
The HJ15ex8.5 B KRSE-V is ideally suited for diverse challenging outdoor shooting situations because it can stabilize a broad range of vibration frequencies. Examples range from the low-frequency vibrations encountered on a camera operator's shoulder in a crowd situation, to tripod-mounted operation on shaky platforms, to the higher-frequency vibration that cameras are subject to when operated on vehicles, motorbikes, boats, or helicopters. Four selectable stabilization modes are available to facilitate optimization of the degree of correction under diverse, and sometimes unique, shooting conditions.
The effectiveness of the image stabilization system was highlighted in the coverage by a major European production company of the Tour de France, whose camera operator was shooting hand-held from a motorbike pillion, and consistently delivered rock-steady close-ups of the cyclists even on very uneven roads.
