Canon offers a variety of Broadcast ENG/EFP lenses, including both HDTV and SDTV versions. All Broadcast ENG/EFP lenses are equipped with Canon’s new “xs” technology as well as our original “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 it’s size or weight. |
