XJ75x9.3BIE Lens

The XJ75x9.3BIE-D is a popular long field lens in the emerging fleets of HDTV mobile television facilities. Canon recognized the broad diversity in imaging needs of mobile trucks that cover all forms of sports and entertainment events and has built up a flexible family of long zoom lenses to flexibly address this wide range of production projects. In doing so, they harnessed the best in optical, mechanical, and digital technologies to implement a long zoom lens that remains modest in its size and weight.

This lens is intended for mobile truck operators, broadcasters, and major venue operators having as their foremost priority the long telephoto flexibility for high definition sports and entertainment event coverage – but at a lower budget level. It can equally service the special needs of government (homeland security) and many institutional sectors of the market that might also have long telephoto as a priority.

The XJ75x9.3BIE-D design applied the most state of the art in Canon optical technologies to achieve a very long focal length range. Canon’s renowned engineering design optimization strategies were once again brilliantly applied to the unique technological challenges of providing full HDTV image quality while implementing control of focal length over the challenging range from 9.3mm to 700 mm (up to 1400mm with extender). The design paid particular attention to streamlining the ergonomics and physics of such a daunting optical system. The built-in optical image stabilization system (that makes such an unprecedented focal range practical) has been retained even in this lower cost telephoto lens.

The optimizations within the optical design successfully maintain a high MTF profile over the entire image plane when exercising the wide 75:1 focal length change. A parallel optimization paid close attention to minimizing chromatic aberrations over this same focal range. Recognizing the especially challenging nature of sports and event coverage (that regularly encounter challenging low scene lighting) the lens designers also gave a special priority to achievement of an impressive maximum relative aperture of f 1.7.
