1/3” Powerful ENG Lens for Limited Budget HD Productions

The KT17ex4.3B IRSE is specifically designed for users whose foremost priority is a 1/3" lens that delivers a generous range of focal lengths combined with a wide field of view in a lightweight mobile package. The lens design is a fine compromise between the demands for ruggedness and mobility in a handheld camera system and the high imaging performance requirements for HD News and limited budget HD productions. An important aspect of this lens is the cost optimized design concept. Customer recommendations combined with evolving optical design strategies and materials produced a new definition in price performance ratio for HD ENG acquisition systems that guided the design of the new KT17ex4.3B IRSE.

Optical Technologies

Newly developed optical glass materials each having unique dispersion characteristics allowed improved control over chromatic aberrations and geometric distortion. Lens element surface accuracy has been improved two-fold over those in the earlier HDgc lenses contributing to the improved MTF performance New Multilayer Optical Coatings combined with new deposition processes produce an improved optical contrast ratio Three-part Internal Focus is a Canon design innovation that reduces changes in aberrations when focusing to different object distances while also exercising improved control over any tendency for focus breathing New and more powerful computer design tools facilitated a greater degree of optimization of multiple optical variables in the lens design

Digital Technologies

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.
