Features

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-IFxs logo identifies the deployment of these technologies in the lens.
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 floating optical system to better control chromatic aberrations
Crossover Technology – switchable operation between 16:9 and 4:3 aspect ratio imagery
New third-generation enhanced digital servo systems using Canon-developed 16-bit optical rotary encoder devices introduce entirely new value-added creativity to handheld acquisition systems
Enhanced Digital Drive technology – encompasses a microcomputer driven servo control that embodies position memory and user-defined digital functionality to significantly empower the camera operator charged with creative shaping of the image presented to the camera sensors
16-bit rotary encoders ensures high precision and repeatability of the Zoom and Focus settings
16-bit rotary encoder for aperture control reports to the associated camera Iris control system (10-bit compatibility)
Maximum Zoom speed is 0.5 seconds and Focus is 1.5 seconds
Technologies – ergonomic mechanical design produced a truly compact (238mm long) lens
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 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 from all components comprising the composite lens system.
