The KT17ex4.3B IRSE is a 1/3" portable HD standard lens specifically designed to support a range of corporate and business industrial applications.
The KT17ex4.3B IRSE offers a focal length of up to 73mm (or 146mm with extender) and a wide-angle of almost 62.9 degree angular field of view in the 16:9 HDTV image format. The lens features a 17x zoom ratio and has a minimum focal length of 4.3mm. This lens can encompass an unusually broad range of shooting situations, and offers excellent operational capabilities at a very affordable price in a compact package weighing 1.48kg.
The lens has high MTF over the entire image plane, minimization of chromatic aberrations, and maximization of image contrast. Relative light distribution is optimized for the more open aperture settings and uniformity of brightness across the image plane combined with the high contrast and excellent picture sharpness produces vividly clear HD pictures. Contrast is extended - flare, veiling glare, and any internal reflections have been substantially reduced. It has tight control of the geometric distortion at wide-angle settings and spectral transmittance characteristic adheres to HDTV colorimetric standards.
Newly developed optical materials combined with the very latest lens element design innovations and multilayer coatings - that produce an unsurpassed pristine imaging system for the most discerning production team.
A Canon design innovation that uses a floating optical system to better control chromatic aberrations.
Enhanced Digital Drive technology
16-bit rotary encoder for aperture control reports to the associated camera Iris control system (10-bit compatibility).
Maximum Zoom speed is 1.2 seconds over the entire range.
