Canon KJ10ex4.5B Overview

The Canon KJ10ex4.5B IASE A 2/3" Portable ENG 10x Zoom Lens is a portable HDTV production lens within the 1/2-inch image format sector of the HDgc family. This particular lens delivers a generous range of focal lengths from 4.5 to 90mm with the built-in 2x extender and a wide field of view of almost 62 degrees horizontal in a lightweight (4 lbs) mobile package. Additionally the KJ10ex4.5B also comes equipped with a servo zoom and servo/manual focus.

The KJ10ex4.5B utilizes computer-aided design techniques to produce a very wide-angle HDTV lens. It is a design directly responding to the expressed creative desires of broadcasters and HD producers for more versatility in an HD acquisition system. The KJ10ex4.5B represents a compromise between the demands for mobility in a handheld HDTV camera system and the high imaging performance requirements for HDTV production. The KJ10ex4.5B has a high MTF (Modulation Transfer Function) over the entire image plane, minimization of chromatic aberrations, and maximization of image contrast. Relative light distribution was optimized for the more open aperture settings and this uniformity of brightness across the image plane combines with the high contrast and picture sharpness to produce crisp and clear HD pictures.

Lens Design

  • Aspheric lens optics utilizing Flourite and Hi-UD glass with multilayer coating for sharp clear images and improved resolution corner to corner
  • Internal foucs for constant lens volume
  • Materials and substances potentially harmful to the environment are avoided in the lens construction

Digital Servo System

  • Framing Preset
    • Allows you to preset a focal length into either of the two lens memories
    • A simple push of a button allows you to zoom the lens to that preset
    • The digital drive ensures repeatable zoom positions to 0.1 micrometer
    • The zoom speed can be varied as desired without affecting the accuracy of the zoom
  • Speed Preset
    • Allows you to set a repeatable zoom speed
  • Shuttle Shot
    • The digital servo system can "shuttle" the lens between any memorized focal lengths two points in either direction
  • 16-bit Rotary Lens Encoder
    • Encodes Focus, Iris and Zoom
    • Allows for precision repeatable zoom, focus and iris pulls accurate to 0.1 micrometer
    • The lens requires no modifications to be used with virtual digital studios
