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
complex scenes.


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.

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

Las Vegas.

“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
challenging situations,”

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

poor lighting

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
servo control.

An additional button
provides three modes of operation:

Part-Time – actuates the auto-focus system as long as a control button
is depressed.

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.

(The Canon

DIGISUPER 100xs was the world’s first triple-digit
HD zoom lens.)

All Canon
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).

The new DIGISUPER 100AF and DIGISUPER 86AF long-field HD auto-focus zoom
lenses are

Canon’s latest
advancements designed to provide camera operators with the industry’s most
sophisticated tools for television production.
