Please mouse over each part of the nomenclature to see it explained. Four significant technologies converge to produce
the KT20x5B KRS portable HD production lens system that has been
tailored to partner with today’s highest performing HDTV portable
cameras and camcorders:
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.
- 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 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
such as cadmium, mercury, PBBS etc from all components comprising
the composite lens system.
