| Canon is introducing a new series of e-lFxs / e-HDxs lenses, which are equipped
with a new enhanced digital drive unit. Conventional potentiometers are analog
positional sensors capable of only 8-10 bit equivalent resolution. Thus virtual
ENG studio systems called for an optional Encoder Unit to be put on the zoom
and focus ring of the lens. With the introduction of 16 bit resolution Rotary
Encoder Devices built into the new enhanced digital drive unit, the lens can
be simply integrated into a virtual digital studio system without any additions.
The encoders also enable superior precise control. The zoom servo provides a
dynamic range of 0.5 sec quick zooms to an over 3 min. super slow zoom. Repeatability
in focus and iris control are also much more precise. Canon’s unique technology
has made the Encoder Device surprisingly small to be installed in the existing
drive unit without changes in size or weight. |
