The J35x11B and the companion highly telephoto J35x15B represent the pinnacle of Canon portable standard definition EFP lens design. They are strategic members of the family of five portable ENG/EFP lenses designed to support high-performance analog NTSC and digital SDTV production � that collectively offers an unusually broad range of creative options.
These telephoto lenses are intended for producers and broadcasters engaged in documentary, natural history, and the many other challenging field productions that seek superb image capture in remote locations and from considerable distances. Aerial shooting, sports and entertainment coverage, portable acquisition in arduous terrain � are all superbly supported by these stalwart telephoto portable SDTV lenses.
ABOUT THIS LENS
The J35x11B and the companion J35x15B are a standard definition EFP lens family that brings entirely new shooting flexibilities to NTSC and SDTV field production. The J35x11B can extend to 770mm with the extender while the J35x15B can achieve an unprecedented 1050mm (with extender). Both lenses represent the very best in optical and mechanical design.
They represent an excellent marriage of needs for creative flexibility and mobility in a handheld camera system with the demanding performance requirements for high-end image acquisition at unusually long focal lengths. The design optimization strategies adopted a novel dual lens approach to broaden the shooting options, and sought achievement of an adequate sensitivity, maximization of image contrast, and preservation of the highest MTF over the extended 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.
