The Canon HDgc KH16x5.7-IRSE is a 16x lens designed for the 1/2" CCD line of XDCAM HD cameras by Sony. As HDTV becomes the standard for television broadcasts, more production facilities are looking to originate projects in high definition. A variety of formats have been introduced to fill the gap, including both HDV and XDCAM HD. Sony's XDCAM HD cameras provides a low-cost alternative to the higher priced 2/3" cameras, while still maintaining the same familiar ENG/EFP workflow. This 1/2" lens provides high definition optics that will fully realize the capabilities of XDCAM HD, while still being cost effective for lower budget productions. The KH16x5.7-IRSE is a perfect balance between performance and portability, equipped with features such as internal focus and shuttle-shot programmable positioning. The focal-length range is 5.7-92mm with a minimum object distance of 0.6 meters (2 feet) and comes with a 2x extender for increased telephoto capability.
