HJ17ex7.7B ITS-RE/ME
HDTV Remote Control Lens

The HJ17ex7.7B 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 HDTV performance.

The HJ17ex7.7B ITS utilized breakthrough technologies and powerful computer-aided design techniques to produce a very wide-angle HDTV lens in a modest 4.3 lb package. It is a design directly responding to the expressed creative desires of broadcasters and HD producers for a truly versatile HD 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 HJ17ex7.7B represents an excellent compromise between the demands for compactness and lightweight in a remote controlled acquisition system and the exacting performance requirements for high-end 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 the highest MTF at the wider angle focal lengths (where scene detail can be particularly high) was a special priority.
