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.
