Listing description

HJ14ex4.3 IASE (HJ14ex43IASE) super wide angle 2/3inch HD zoom lens 4.3-60mm with 2x extender & e-digital drive unit with encoder;Widest Angle Lens To Date in the TV Industry;With a minimum focal length of 4.3mm the HJ14ex4.3 lens features the widest angle among presently available 2/3-inch lenses with an angular field of view of 96.3° in the 16:9 format at the wide end. This is significantly augmented with the 14x zoom range reaching to 60mm(120mm with extender), producing an unsurpassed operational combination that greatly expands HDTV production applications.;Improved Optical Performance;The past decade has seen dramatic advances in powerful new 3D optical design tools, glass materials, design techniques (such as aspherical elements), and optical coatings. These new technologies allow the HJ14x lens to provide a wider angle and a higher zoom ratio than previous models, while also offering important optical performance enhancements;Higher resolution at both picture center and at the extremities of the 16:9 HD image plane;Further minimization of chromatic aberrations and geometric distortion;Less light falloff from picture center to corners, especially at wide angle settings;Reduced focus breathing;Curtailment of ghosting artifacts created by strong light sources;Improved Operabilty and Reduced Operator Fatigue;Besides the exceptional optical performance, another remarkable character of this new lens is it’s newly designed drive unit. With the goal of pursuing ease of operation, Canon has reached a new design based on human ergonomics, refined by a long term research and testing.;Power Optics – superb imagery with latest optical design;Focal range of 4.3mm to 60mm (120mm with extender);Crossover Technology Option – switchable between 16:9 and 4:3;Enhanced Digital Drive technology;Compact, robust ergonomic design;Features;Wide angle portable ENG/EFP lens;The short 4.3mm focal length provides a 96.3 degree horizontal angle of view for the 16:9 HD image format. Combined with a focal range that has been extended to now cover a range from 4.3mm to 60mm (and 120mm with extender) this lens offers unsurpassed operational capabilities in a compact package of 1.99kg. The maximum relative aperture is F1.8. Additionally, focus breathing has been significantly reduced over its predecessor the HJ11ex4.7B.;Minimization of monochromatic and chromatic aberrations and further maximization of image contrast combine with improved MTF. The relative light distribution over the mid-to-long focal lengths with better uniformity of brightness across the image plane also provides the higher contrast. These combinations ultimately produce vividly clear and superb sharp HD pictures.;Optical Technologies;Newly developed high index optical glass materials and the Aspheric Lens Elements allow improved control over chromatic aberrations and geometric distortion especially at the very wide angle settings. Canon’s three-part Internal Focus innovation reduces changes in aberrations when focusing to different object distances while also exercising tight control over any tendency for focus breathing.;Digital Technologies;New Enhanced Digital Drive technology 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.Dynamic Zoom Speed Range can be adjusted from 0.5 seconds to 5 minutes (from wide to telephoto extremes).;Optomechanical Technologies;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;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.
