Four significant technologies converged to produce the HJ14ex4.3B portable HD production lens system that has been tailored to partner with the most contemporary of high-end 2/3-inch HD production cameras:
Newly developed high index optical glass materials, each having unique dispersion characteristics, allowed improved control over chromatic aberrations and geometric distortion. Lens element surface accuracy has been improved two-fold over those in the earlier HJ11ex4.7B lens contributing to the enhanced MTF performance New Multilayer Optical Coatings combined with new deposition processes produce an unsurpassed pristine imaging system for the most discerning production team Aspheric Lens Elements are deployed to a greater extent in the larger diameter elements and they contribute to far greater control over geometric distortion and aberrations especially at the very wide angle settings Three-part Internal Focus is a Canon design innovation that reduces changes in aberrations when focusing to different object distances while also exercising tight control over any tendency for focus breathing New, more powerful computer design tools facilitated a greater degree of optimization of multiple optical variables in the lens design
New, fourth-generation digital servo systems further empower the camera operator in terms of operational creativity: Enhanced Digital Drive technology based upon a totally new software platform provides precision microcomputer control of the three servo systems for zoom, iris and focus while also facilitating new developments in lens-camera correction of lateral chromatic aberration Unique Information Display and extended memory within the digital drive unit extends user-defined digital functionality Canon?s patented Micro Roofmirror Array (MRA) technology underlies the unique miniature 16-bit rotary encoders that are used for each of the zoom, iris, and focus position detection (each with a positional accuracy of 0.1 micrometer) Dynamic Zoom Speed Range can be adjusted from 0.5 seconds to 5 minutes (from wide to telephoto extremes)
Extensive use of 3D CAD-CAM design facilitated an imaginative ergonomic design that paid high attention to operator comfort and lessening of fatigue during protracted shooting: Digital Drive Unit was totally redesigned to take into account the curved human hand that encompasses the unit, with a view of shaping the unit for greater comfort and to better facilitate the actuation of lens controls. The unit shape also provides a wider separation that allows the other hand to more easily adjust the focus control. Finally, the drive unit was narrowed and its mounting angle on the lens set to allow the operator?s elbow to settle close to the body thus providing an important reduction in fatigue when operating a shoulder mounted lens-camera system Special Magnesium alloy body for light weight and exceptional durability Computer simulation of the optomechanical design allowed examination of optimized anti-reflection internal barrel coatings, and structural techniques (light blocking grooves and knife edges) that produced greater control over harmful light reflections within the lens barrel that can be stimulated by strong light sources
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.
