picture detail contained in H
igh Definition television (HDTV) makes anything in less-than-perfect
focus immediately obvious.
As a result,
shooting HD video poses new challenges for camera operators, who must
pay close attention to picture framing and physical control of their camera and
lens, while also continually maintaining sharp focus of selected objects within
Inc.’s extensive experience in long-zoom HD field-lens design provides a unique
understanding of the challenges that HDTV presents to camera operators, which
is why Canon developed a powerful new automated solution to assist in the task
of maintaining constant and perfect HD lens focus.
The new Canon DIGISUPER 100AF and DIGISUPER
86AF* auto-focus long-field HD zoom lenses feature sophisticated auto-focus
capabilities based on a proprietary HD implementation of Through-the-Lens
Secondary Image Registration Phase Detection Method technology.
These new lenses will be featured at the
Canon booth #SU 3020 at NAB2007, the annual convention of the National
Association of Broadcasters, held April 14-19 in
“Our new DIGISUPER 100AF and DIGISUPER 86AF lenses are designed to help
camera operators ensure that their shots are always in exact focus, even in
said Gordon Tubbs, director, Broadcast and Communications division, Canon
“These lenses assist camera operators to
create the highest quality video images possible – operators know they can
always achieve exact focus with the push of a button.
This is especially helpful in situations where
the operator is unsure due to
or cannot otherwise determine exact
focus just by looking at the viewfinder.
addition to the Part-Time focus-check mode there’s a Full-Time mode to help
camera operators during long shoots.
Either way, the Canon
100AF and DIGISUPER 86AF auto-focus lenses enable camera operators to apply
their full attention to the creative aspects of framing HD images and following
the action in the scene,” said Tubbs
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 object operators want to
focus most sharply on in the scene.
Camera operators can change the window’s
position and size by means of a miniature joystick on the camera handle’s focus
An additional button
provides three modes of operation:
Part-Time – actuates the auto-focus system as long as a control button
Full-Time – actuates the auto-focus continually on selected moving
objects such as racing cars (which might be speeding toward the camera
position), or for shooting situations entailing full-servo robotic operation.
Off – allows for normal, unassisted lens focus.
In addition to their auto-focus capabilities, Canon’s new DIGISUPER
100AF and DIGISUPER 86AF long-field HD zoom lenses feature Canon’s highly
acclaimed built-in Optical Image Stabilizer, or “Shift-IS” system, to help
create rock-solid images even at telephoto distances.
The DIGISUPER 100AF and DIGISUPER 86AF lenses are based on Canon’s
DIGISUPER 100xs and DIGISUPER 86xs long-field HD zoom lenses, which are among
the most widely used lenses in HD
sports and entertainment production.
DIGISUPER 100xs was the world’s first triple-digit
HD zoom lens.)
DIGISUPER lenses feature the HD optical precision and heightened long-range
zoom capabilities that have made Canon a global leader.
All of Canon’s DIGISUPER HD field lenses also feature
Canon’s unique XS technology for improved optical performance and lighter
weight, as well as Canon’s
second-generation Digital Servo
System, which provides microcomputer compensation of lens-focus breathing (the
inadvertent alteration of field of view when operating the focus control).

DT-150 HD Canobeam
ramatic growth in HDTV sports and entertainment production, as well as
the need for permanent HD and SD video links at broadcast facilities, has
provided the impetus for a new and versatile uncompressed, high-bandwidth
(HD-SDI and SD-SDI) digital-transmission solution. This solution is known as
the DT-150 HD Canobeam transceiver and is designed for situations where
fiber-optic cables or microwave are impractical and/or the simplicity of Free Space
Optics is preferred.
DT-150 HD Canobeam is the newest
member of Canon’s acclaimed series of point-to-point optical beam transceivers
that use infrared light to bridge gaps in high-bandwidth transmission
situations. The DT-150 HD Canobeam provides bi-directional, uncompressed 1.5
Gbps transmission of embedded digital video, audio, and camera-control signals
on a single HD-SDI or SD-SDI stream with no delay. The DT-150 HD Canobeam can
also 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, camera-control signals, and
robotic camera-control data. The DT-150 HD
has a range of up to one kilometer and — like all Canobeam DT-100 series
products — features Canon’s exclusive Auto Tracking feature to maintain beam
alignment despite vibration due to wind, rain, or unsteady camera platforms.
The DT-150 HD Canobeam has an
estimated selling price of $40,000* per pair.
“This is a
great leap forward for Canobeam, in terms of performance and price,” says
Gordon Tubbs, director of Canon
Broadcast and Communications division. “HD is such a common factor in
everybody’s lives now, especially at most broadcast facilities. By seamlessly
providing users with affordable, wireless, point-to-point uncompressed digital
transmissions, the DT-150 HD Canobeam is playing a major role in
revolutionizing the broadcast industry as the transition to HDTV accelerates.”
HD Canobeam also features an important advance in the Canobeam DT-100 series
with the addition of a Small Form Pluggable (SFP) module system. Use of an SFP
HD module allows the DT-150 HD Canobeam to interface via single-mode fiber LC
connectors. Users who are already using single-mode fiber connections can
simply plug it into the DT-150 HD Canobeam and instantly transmit embedded
video, audio, and camera controls via the FSO connection. Users who do not have
an existing single-mode fiber connection will be able to use third-party media
converters to convert HD-SDI signals or SD-SDI signals from either coaxial or
SMPTE hybrid fiber cable into single-mode fiber for transmission. As with any
SDI stream, audio and/or multiple video signals will be embedded into the
stream via a multiplexer.
all of Canon’s Canobeam products, the DT-150 HD uses Free Space Optics, which
requires no FCC licensing or frequency coordination. Free Space Optics provides
a highly secure and reliable video/audio link that is free from RF interference
and signal interception. Canon’s other DT-100 series Canobeam systems are
proven high-bandwidth data-networking solutions used by corporate and
university campuses, government and military facilities, and other situations
where existing bandwidth is insufficient, fiber is cost-prohibitive or
logistically impossible, or a redundant disaster/recovery system is essential.
HD Canobeam offers multiple applications, from permanent installations
(including such uses as STL), to live HD and SD television events. These events
may include golf matches where ponds and fairways can’t be bridged by fiber
cables, major outdoor concerts where remote camera platforms make fiber links
impractical, or sports where images from manned and robotic cameras may need to
be relayed to a central point from inaccessible locations. With the combination
of Canon’s exclusive Auto Tracking feature and the ability to embed camera
control and robotic control signals into the bi-directional HD-SDI or SD-SDI
stream, the Canobeam DT-150 HD Canobeam is the perfect solution for the
television broadcast and mobile production industry’s
increase in HDTV sports and entertainment telecasts.
