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
encompasses 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
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
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 such as cadmium, mercury, PBBS etc from all components comprising the composite lens system.
