Four significant technologies converge to produce the KH13x4.5 KRS portable HD production lens system that has been tailored to partner with today's highest performing HDTV portable cameras and camcorders:
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. The e-HDxs logo identifies the deployment of these technologies in the lens.
A Canon design innovation that uses a floating optical system to better control chromatic aberration.
Enhanced servo system called Shuttle Shot that adds value-added creativity to handheld acquisition systems.
Advanced Drive technology
Encompasses a servo control that allows the operator to precisely zoom between tow pre-programmed zoom positions Maximum Zoom speed is 1.2 seconds over entire range.
- Mechanical Technologies
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.
- Ecological Design
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.
