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.
