Affordable 2/3 inch HDTV Remote telephoto lens
The KJ20x8.5B KTS has an excellent sensitivity of f 1.8 over a 20x
zoom range (falling modestly to f 2.7 at full telephoto). It has a
generous 58.9-degree horizontal field of view and weighs just
1.27kg (2.8 lbs). This lens is anticipated to be a superb workhorse
that can address a wide range of remote control projects.
The design optimization strategies sought a balanced MTF profile
over the entire image plane at an F4.0 aperture setting. Relative
light distribution was optimized for F2.8 and above and this
uniformity of brightness across the image plane combines with the
high contrast and excellent picture sharpness to produce vividly
clear HD pictures. Contrast was extended by superb control of black
reproduction - with optical and mechanical design innovations that
substantially reduced flare, veiling glare, and any internal
reflections. Similar attention to minimization of ghost images and
other highlight-related chromatic distortions caused by strong
light sources on-axis and off-axis further extend the operational
contrast range of the lens. Highly accurate gear backlash reduction
in order to cope with the high level requirements of SDTV and HDTV
applications.
