A variety of technologies converged to produce the HJ18ex7.6B portable HD ENG 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.
Power Optics - speaks to the combination of specialized materials, contemporary optical design, and multilayer coatings that produce the superb imagery
Internal Focus - a Canon design innovation that uses a focusing system to better control chromatic aberrations while minimizing unfavorable focus-breathing effect.
New enhanced digital servo systems using Canon-developed 16-bit optical rotary encoder devices introduce value-added creativity to handheld acquisition systems
Improved Digital Drive Technology - Encompasses a microcomputer driven servo control that embodies position memory and user-defined digital functionality to empower the camera operator charged with creative shaping of the image presented to the camera sensors
16-bit rotary encoder for aperture control reports to the associated camera Iris control system (10-bit compatibility)
Virtual operation is enabled by a full servo using three 20-pin connectors.
Improved Menu functionality in drive unit
ALAC (auto lens aberration compensation), CAC (chromatic aberration compensation) and other types of camera aberration corrected thanks to rapid start-up and turn-on. Use of an absolute value encoder enables positions to be detected at the same time as start-up. Unlike with a relative value encoder, initializing is not required.
Compact digital servo drive unit is mounted to the lens at a 12.5 degree angle for comfort and balance
Magnesium alloy body for light weight and superb 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
