The HJ11ex4.7B is the widest angle of view portable HDTV production lens offered by Canon. It is a key member of a family of seven HD portable EFP 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 really wide angle shooting with minimum chromatic aberrations and geometric distortion (at the widest angle) – contained within a lightweight mobile package that offers exceptional HDTV performance. The HJ11ex4.7B 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. ABOUT THIS LENS The HJ11ex4.7B represents a magnificent compromise between the demands for mobility in a handheld HDTV camera 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. Relative light distribution was optimized for F2.8 and above and this uniformity of brightness across the image plane combines with the high contrast and excellent picture sharpness to produce vividly clear HD pictures. Contrast was extended by superb control of black reproduction – with optical and mechanical design innovations that substantially reduced flare, veiling glare, and any internal reflections. Similar attention to minimization of ghost images and other highlight-related chromatic distortions caused by strong light sources on-axis and off-axis further extend the operational contrast range of the lens. Tight control of the critically important geometric distortion at wide-angle settings constituted another central design imperative. The lens spectral transmittance characteristic was closely coordinated with that of all of the major portable cameras to ensure adherence to the HDTV colorimetric standards and to additionally support flexible creative control of color reproduction.
