Super telephoto EFP lens
The HJ40x10B and its companion the HJ40x14B represent the pinnacle of Canon portable high definition EFP lens design. Image capture over long distances with extender can achieve 800mm and its focal length of 10mm~400 provides a wide angle that makes it very suitable for sports applications such as golf. The HJ40x10B 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).
