The KJ20x8.5B KTS is an affordable 2/3 inch HDTV telephoto lens that supports a diversity of broadcast, professional, business and industrial remote control applications.
Take a more detailed look into the Canon KJ20x8.5B KTS
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.
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.
Encompasses a 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
Ergonomic mechanical design that produced this HD lens having the same size and weight as its SDTV predecessor Compact drive unit is mounted to the lens at a 12.5 degree angle for comfort and balance Aluminum alloy body for light weight and exceptional durability Internal Focus - a Canon design innovation that uses a floating optical system to better control chromatic aberrations
All Canon Remote Control TV Lenses accept 3 types of Canon standard controllers, as well as standard remote control cables, which are designed to provide different types of zoom, focus and iris remote control. These lenses are also available with a simple interface for use with custom controllers.
