Canon offers a variety of Broadcast ENG/EFP lenses, including both HDTV and SDTV versions. Please note that the HDTV lenses perform excellently when they are used on SDTV cameras. All Broadcast ENG/EFP lenses are equipped with Canonˇs new ¨xs〃 technology as well as our latest ¨Digital Drive〃
e-II Drive Unit with Rotary Encoder
Canon offers a complete series of HDTV ENG/EFP lenses, equipped with the e-II Drive Unit, the next generation drive unit included with the rotary encoders. An encoder is a digital potential detector that makes the zoom/focus control much more precise and repeatable. Also, the Encoders will enable the lens to be simply integrated into a virtual studio system, which usually called for optional Encoder Units to be put on the zoom/focus ring of the lens. By adopting a unique technology, Canon has made the Encoder Device surprisingly small to be installed in the existing drive unit without changing itˇs size or weight.
