Overview
The KJ10ex4.5B IASE S is a portable HDTV production lens within the 2/3-inch image format sector of the HDgc family. This particular lens is intended for users whose foremost priority is a lens that delivers a generous range of focal lengths combined with an exceptional wide field of view in a lightweight mobile package. It was specifically designed for cost-effective 2/3-inch acquisition systems. Canon’s breakthrough technologies and powerful computer-aided design techniques produced the KJ10ex4.5B IASE S, a standard HDTV lens with an excellent performance-cost optimization. In addition, it offers focal lengths of up to 45mm (or 90mm with extender) and a wide field of view of 93.7 degrees. It is a design that directly responds to the continued creative desires of broadcasters and HD producers for low-cost HD acquisition system.
The KJ10ex4.5B IASE S is a fine representation meeting the demands for mobility in a handheld HDTV camera system and the high imaging performance requirements for HDTV production. The requisite optimization strategies to achieve this balance sought a high MTF over the entire image plane, minimization of chromatic aberrations, and maximization of image contrast. Preservation of a high MTF at the wider-angle focal lengths (where scene detail can be particularly high) was a special priority.
Significant technologies converge to produce the KJ10ex4.6B IRSE portable HD production lens system that has been tailored to partner with today's highest performing HDTV portable cameras and camcorders:
- Optical Technologies
Uses optical material and multilayer coating that produce an unsurpassed pristine imaging system for the most discerning production team. - Internal Focus
A Canon design innovation that uses a floating optical system to better control chromatic aberrations. - Advanced Drive technology
Encompasses servo control that allows the operator to precisely zoom between tow pre-programmed zoom positions. Maximum Zoom speed is 1.2 seconds over entire range. - Mechanical Technologies
Ergonomic mechanical design that produced this HD lens having the same size and weight as its SDTV predecessor. Compact drive unit is mounted to the lens at a 12.5 degree angle for comfort and balance Aluminum 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 such as cadmium, mercury, PBBS etc from all components comprising the composite lens system.
