Achieve a 500mm telephoto image capture with a handheld HD lens and camera. The 2x extender will take this to 1000mm opening up dramatic possibilities in wildlife shooting, special news events, sports and many other applications.
The adoption of new optical materials and contemporary optical design technologies have facilitated the production of a groundbreaking portable lens that significantly adds to the creative arsenal available to the HD production communities. The novel 3-group inner focus system design in particular was central to achieving the extra telephoto range while controlling multiple optical aberrations. High sharpness and contrast is maintained over this impressive focal range, while achieving a lightweight compact physical dimensions.
New third-generation enhanced digital servo systems using Canon-developed 16-bit optical rotary encoder devices introduce new 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. A 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.
