Wexler has purchased Canon's new HDgc lenses to complement the company's recent acquisition of the Sony XDCAM HD optical disc camcorders. Canon's new HDgc line of lenses is specially engineered to complement the new generation of mid-range HD cameras that manufacturers are introducing to meet the expanding market for HDTV programming. Wexler's HDgc lens purchase includes Canon's KH21ex5.7 IRSE telephoto lenses and Canon's KH10ex3.6 IRSE wide-angle models.
The new HDgc lens line combines many of the optical features of Canon's higher-end HDxs lenses, yet is also designed in direct relation to the imagers and pricing of the new generation of tapeless HD camcorders. The KH21ex5.7 IRSE telephoto lenses and KH10ex3.6 IRSE wide-angle lenses purchased by Wexler are designed for the half-inch CCD imagers of Sony's new XDCAM HD optical disc camcorders. The KH21ex5.7 IRSE lens features a 21X zoom ratio and a 2X extender, suitable for both ENG and EFP applications. The KH10ex3.6 IRSE lens offers a 3.6mm wide angle, a 10X zoom ratio, and a 2X extender.
In addition to the KH21ex5.7 IRSE and the KH10ex3.6 IRSE lenses, Canon's new HDgc lens line will also include a 16X standard lens to be introduced later this year for half-inch CCD cameras. Also in the HDgc line are the more economical KH20x6.4 KRS lens (also for half-inch HD CCD cameras) and the KJ20x8.5B KRS lens (for 2/3-inch HD CCD cameras)
. As with Canon's higher-end HDxs lenses, HDgc lenses feature many outstanding Canon optical features, including reduced chromatic aberration and a high and well-controlled MTF (Modulation Transfer Function) profile over their entire respective image planes. HDgc lenses also incorporate special elements without lead to minimize the impact on the environment, including "Flourite" with extraordinary dispersion characteristics and the newly developed Hi-UD (high index ultra low dispersion) glass.
The KH21ex5.7 IRSE, KH10ex3.6 IRSE lenses, and forthcoming 16X standard HDgc lenses also include Canon's acclaimed "eDrive" feature, which utilizes three Canon ultra-high-precision, microprocessor-driven digital servos with miniature 16-bit optical encoders. Canon's eDrive technology represents an entirely new way to control portable lenses. With eDrive, users can easily program such functions as zoom and focus settings into a lens for precise, automated repeatability via an easy-to-use LCD menu, assignable "soft" function buttons, and the rocker switch built into the lens grip. Users can program multiple settings or none at all, depending on their personal needs and preferences.
The KH20x6.4 KRS and KJ20x8.5B KRS lenses feature Canon's exclusive Shuttle Shot function, an advanced servo system that facilitates zooming back and forth between any two focal length positions and brings an entirely new range of value-added creativity to hand-held acquisition systems. These two lenses also feature a new ergonomic drive unit that achieves an ideal balance in comfort and operation.
