Canon HJ40X14B IASD-V HDTV EFP Lens

The HJ40x10B and the companion HJ40x14B are a high definition EFP lens family that brings entirely new shooting flexibilities to field production. The HJ40x10B can extend to 770mm with the extender while the HJ40x14B can achieve an unprecedented 1120mm. Both lenses represent the very best in optical and mechanical design and their unique optical image stabilization systems make possible the capture of rock steady high definition imagery under the most adverse of field conditions. They represent an excellent marriage of needs for creative flexibility and mobility in a handheld HDTV camera system with the demanding performance requirements for high-end HDTV image acquisition at long focal lengths. The design optimization strategies included a dual lens approach to broaden the shooting options, achievement of an adequate sensitivity, maximization of image contrast, and preservation of the highest MTF over the long focal ranges. High contrast is ensured 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.
