Canon Lenses Descend On Beijing For NBC Olympics Coverage

Broadcast is the exclusive provider of HD lenses to NBC Olympics for its
coverage of the Games of the XXIX Olympiad. NBC also used the Canobeam DT-150
HD Free Space Optics video transceiver system for transmitting “beauty shots”
of Beijing back
to NBC’s Olympic broadcast facility.

“This was the seventh consecutive Olympics that NBC has entrusted Canon to be
our exclusive lens provider,” says Dave Mazza, senior vice president,
engineering, NBC Olympics. “This is not something we take lightly. We only get
one shot at capturing each moment of competition and emotion at the Olympic

Mazza says the latest features of the DIGISUPER 100AF long-field auto-focus HD
zoom lens and the economics of the DIGISUPER 22xs compact studio ‘box’ lens
both fit right into NBC’s production requirements.

The Canon DIGISUPER 100AF and DIGISUPER 86AF lenses (model numbers XJ100x9.3B
AF and XJ86x9.3B AF, respectively) create an operator-controllable window in
the HD camera’s viewfinder that targets the scene subject that operators select
for sharpest focus. Camera operators can change the window’s position and size
by means of a miniature joystick on the camera handle’s focus servo control.

NBC also is using Canon’s DIGISUPER 75xs long-field HD zoom lens and Canon
DIGISUPER 22xs HD studio lenses. Officially designated as the model XJ22x7.3B
IE-D, the DIGISUPER 22xs Compact Studio HD lens weighs just 13.4 lbs., which
provides an appropriate HD studio lens/camera package that can be supported on
a modest-size pedestal or a sturdy tripod system.
Portable HD lenses chosen by NBC Olympics included Canon’s HJ11ex4.7B IRSE
wide-angle zoom, the HJ22ex7.6B IRSE long-focal-length zoom, and the HJ40X10B
IASD-V highly telephoto, image-stabilized HD EFP lenses.

Also on hand is Canon’s Canobeam DT-150 HD video transceiver, the newest member
of Canon’s acclaimed series of point-to-point Free Space Optics transceivers
that use infrared light to bridge gaps in high-bandwidth transmission
situations. The Canobeam DT-150 HD video transceiver provides bi-directional,
uncompressed 1.5 Gbps transmission of embedded digital HD video, audio, and
camera-control signals on a single HD-SDI stream with no delay. It can relay
embedded HD-SDI and SD-SDI video from multiple cameras or other HD/SD video sources,
along with embedded return video and audio to the camera operator, and even
robotic camera-control data. In dense, RF-heavy urban environments such as
Beijing and other major cities, the Canobeam DT-150 HD offers a major advantage
in that it requires no frequency licensing or coordination and it sets up
