4.5 wide-angle lens with x10 zoom and duplicator. Focal length 4.5 to 45mm without duplicator and 9 to 90mm with duplicator. The Canon KJ10ex4.5B incorporates Canon's original Enhanced Digital Drive, a drive unit equipped with information display and digital function selector, so that the user can customize digital functions much more easily and accurately. The new design allows the user to take full advantage of digital features. 

Special features: 

  • Shuttle Shot: Memorizes any two focal lengths, the digital motor can automatically "move" between the two points, in any direction. 
  • Framing preset: A viewing angle can be preset in either memory and the lens will zoom to that position at the push of a button. During a performance, the framing preset will reproduce the zoom position that was decided in the rehearsal. It's easy to repeat the same zoom as many times as you want at maximum speed or at a preset zoom speed. 
  • Speed preset: A specific zoom speed can be preset in memory and the zoom speed can be repeated as many times as desired by pressing a button.

The KJ10ex4.5B features an enhanced digital control unit. Conventional potentiometers are analog position sensors, capable of providing a resolution equivalent to 8-10 bits. With this technology, portable virtual studio systems required an encoder to be placed on the zoom and focus ring of the lens. With the introduction of 16-bit resolution rotary encoders built into the new control unit, the lens can be easily integrated into a virtual digital studio system without the need for add-ons.

The encoders also allow for much more precise control. The zoom servo provides a dynamic range from 0.5sec. to over 5min. of super slow zoom. Repeatability in focusing and iris control are also much more precise. Canon's technology has made the coding device surprisingly small, to be installed in the existing drive unit with no changes in size or weight.
