Wide angle 1/2" portable HD lens
The KH20x6.4 KRS used contemporary optical design criteria to achieve an excellent multipurpose HD lens offering focal lengths up to 128mm and a wide-angle of 57 degrees horizontal. Combined with an exceptionally high sensitivity (F1.4 maximum aperture) this is a lens that offers excellent operational capabilities at a very attractive price in a light compact package weighing 1.27kg.
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 servo system called Shuttle Shot that adds value-added creativity to handheld acquisition systems.
Advanced Drive technology - encompasses servo control that allows the operator to precisely zoom between two pre-programmed zoom positions.
Maximum Zoom speed is 1.2 seconds over entire range.
Auto focus drive system is built into the lens and this interfaces via a serial digital link to the Sony cameras where the auto focus detection system is incorporated.
