Canon HJ14ex4.3BIRSE

Canon HJ14ex4.3BIRSE

The Canon HJ14ex4.3B lens is the most advanced HDTV wide angle lens with unique technology. The HJ14 lens features the widest angle in the industry by the focal length of 4.3mm and the angular field of view of 96.3°(2/3,16:9) at wide end.

By using the latest 3D design technology and large aspherical elements which creates a unique optical layout, the HJ14ex keeps high resolution from the center to each corner of the picture which exeeds the performance of all previous models. The 14x zoom ratio reaches 60mm (120mm with extender) which greatly expands the video possibilities.

As well as being the widest lens in the broadcasting industry, the Canon HJ14ex4.3 has been ergonomically designed for ease of operation.

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.
