Super telephoto EFP lens
The HJ40x14B and its companion the HJ40x10B represent 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 p
