Canon HJ14ex4.3B IRSE HDTV Zoom Lens f/1.8 - B4 Mount

The short 4.3mm focal length translates to 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 weighing less than 4.5lbs. Additionally, focus breathing has been significantly reduced over the predecessor lens.

The maximum relative aperture is f/1.8, a modest but important enhancement over the f/1.9 optical speed of its predecessor (HJ11ex4.7B). The image performance strategies of this new lens sought a tighter control of MTF across the entire image plane and with operational variations of zoom, iris, and focus. Minimization of monochromatic and chromatic aberrations and further maximization of image contrast combine with the improved MTF to produce superb picture sharpness

Relative light distribution over the mid-to-long focal lengths has been more tightly controlled and this better uniformity of brightness across the image plane combines with the higher contrast and excellent MTF to produce vividly clear HD pictures. Contrast was enhanced by excellent control of black reproduction using new multilayer anti-reflective optical coatings and new optomechanical design innovations that significantly reduced flare, veiling glare, and any internal reflections. Of special note is the further minimization of ghosting artifacts and other highlight-related chromatic distortions caused by strong light sources on-axis and off-axis that further extend the operational contrast ratio of the lens.

Despite the extension of the wide angle of view capability of the HJ14ex4.3B, the critically important geometric distortion at wide-angle settings has been tightly controlled. The lens spectral transmittance characteristic was closely coordinated with that of all of the major portable HD cameras to ensure adherence to the international HDTV colorimetric standard.
