The KH13x4.5 KRS is a portable HDTV production lens within the 1/2-inch image format sector of the HDgc family. This particular lens is intended for users whose foremost priority is a lens that delivers a generous range of focal lengths combined with an exceptional wide field of view in a lightweight mobile package. It was specifically designed for the new cost-effective 1/2-inch acquisition systems. In addition, it offers focal lengths of up to 59mm and a wide field of view of 75.7 degrees.
• Optical Technologies
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.
• Internal Focus
A Canon design innovation that uses a floating optical system to better control chromatic aberrations.
• Control Technologies
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.
