J11ex4.5B ITS-RE/ME
HDTV Remote Control Lens

The J11ex4.5B ITS is wide angle of view portable lens offered by Canon to support diverse remote imaging applications including teleconferencing, distance learning, and specialized broadcasting applications. It is a member of a family of six HD and SD remote control lenses that collectively offer an unusually broad range of creative options.

This particular lens is intended for producers and broadcasters having as their foremost priority wide angle shooting with a lightweight mobile production lens-camera system that offers exceptional SDTV performance.

The J11ex4.5B ITS utilized breakthrough technologies and powerful computer-aided design techniques to produce a very wide-angle SDTV lens in a modest 4.3 lb package. It is a design directly responding to the expressed creative desires of producers for a truly versatile acquisition system. The optional flexibility of Canon’s Crossover aspect ratio switching system makes it a superb performer for both 16:9 widescreen and standard 4:3 image formats.

The J11ex4.5B represents a magnificent compromise between the demands for mobility in a handheld SDTV camera system and the exacting performance requirements for high-end SDTV 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 the highest MTF at the wider angle focal lengths (where scene detail can be particularly high) was a special priority.
