The KT20x5B KRS is a 1/3" portable telephoto lens that provides great optical performance and value.
Take a more detailed look into the Canon KT20x5B KRS
The KT20x5B KRS is a 1/3" portable HD standard lens specifically designed to support a range of corporate and business industrial applications.
The KT20x5B KRS offers a focal length of up to 100mmm and a 52 degree angular field of view. The lens features a 20x zoom ratio and has a minimum focal length of 5.0mm. In addition, it is combined with an exceptionally high sensitivity (F1.4 maximum aperture), and can encompass an unusually broad range of shooting situations, and offers excellent operational capabilities at a very affordable price in a compact package weighing 1.19kg.
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.
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
All contemporary Canon lenses avoid the use of materials and substances potentially harmful to the environment. Lead has been removed from all optics and other identified substances from all components comprising the composite lens system.
