The HJ40x14B represents the pinnacle of Canon portable high definition EFP lens design. Image capture over long distances is unprecedented and with extender this lens can achieve a 1120mm. The HJ40x14B represents the very best in optical and mechanical design and its unique optical image stabilization systems make possible the capture of rock steady high definition imagery under the most adverse of field conditions. Aerial shooting, sports and entertainment coverage, portable acquisition in arduous terrain and under dynamic environmental situations (heavy winds) – are all superbly supported by this stalwart HD lens.
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.
Optical Technologies
Power Optics – combination of specialized materials, contemporary optical design, and multilayer coatings that produce the superb imagery
Internal Focus – a Canon design innovation that uses a floating optical system to better control chromatic aberrations
Digital Technologies
New third-generation enhanced digital servo systems using Canon-developed 16-bit optical rotary encoder devices introduce new creativity to handheld acquisition systems. Enhanced Digital Drive technology – encompasses a microcomputer driven servo control that embodies position memory and user-defined digital functionality to significantly empower the camera operator. A 16-bit rotary encoder for aperture control reports to the associated camera Iris control system (10-bit compatibility).
Mechanical Technologies
Magnesium alloy body for light weight and exceptional durability
Ecological Design
All contemporary Canon lenses avoid the use of materials and substances potentially harmful to the environment. Lead has been removed from all optics and other identified substances from all components comprising the composite lens system.
