Optical Performance with an 86x

Zoom Ratio and improved Wide Angle

The DIGISUPER 86II xs & DIGISUPER
86II TELE xs are an extraordinary field
lens that utilizes Canon's new optical
design concept "POWER OPTICAL
SYSTEM" and " -Element".
By adopting this new technology and
concept, the DIGISUPER 86 xs realizes
the necessary optical performance for
HDTV, with increased zoom ratio of 86x,
improved wide angle of 9.3mm while still
maintaining the size equivalent to that of
current SDTV lenses.

-Element & POWER OPTICAL

SYSTEM

Canon has developed this breakthrough
optical design concept using a newly
developed optical element in the most
effective way.
We have named this design concept the
"Power Optical System" which achieves
higher specifications and quality using the
optical " -Element" which virtually
eliminates aberrations.

Image Stabilizer

The history of field lenses is a history of
zoom ratio/focal length extension. It came
to a point where the industry thought it

would be impossible to push the envelope
any further. The telephoto focal lengths of
the lens got so long that even the slightest
amount of wind or operator movement
would cause image shake and viewing the
picture became intolerable, this was before
Canon announced the incredible
magnification DIGISUPER 86 xs zoom
lens. Canon, renowned for its optical
image stabilization technologies,
developed another new stabilization
solution for the broadcast field lens, a
built-in Optical Shift Image Stabilizer
(Shift-IS) to overcome image shaking at
telephoto focal length. Now the Shift-IS is
employed in the DIGISUPER 86II xs &
DIGISUPER 86II TELE xs.

"CAFS" Constant Angle Focusing
System

The zooming effect of focus is the
phenomena where the picture size (angle
of view) changes when focusing
(breathing). However, a 32bit CPU
calculates and controls the zoom when
focusing in order to counteract these
phenomena. Thus the DIGISUPER 86II xs
& DIGISUPER 86II TELExs have zero
zooming effect of focus throughout the
whole zoom range.

Latest Generation DIGITAL SERVO
SYSTEM

Canon's latest generation digital servo
system allows the use of many new
functions such as constant angle of view
while focusing "CAFS" and the selection
of different servo characteristics.
These functions are only possible with a
digital servo system. In addition to these
new functions, the upgrading of software
will be possible when new functions
become available in the future. This
means that the DIGISUPER 86II xs &
DIGISUPER 86II TELExs have
unlimited possibilities.

Image Stabilizer

How the Optical Shift Image Stabilizer (Shift-IS) Works

When the lens moves, the light rays from the subject are bent relative to the optical axis, resulting in an
unsteady image because the light rays are deflected. By shifting the IS lens group on a plane perpendicular to
the optical axis to counter the degree of image shake, the light rays reaching the image plane can be steadied.
Since image shake occurs in both horizontal and vertical directions, two shake-detecting sensors for yaw and
pitch, detect the angle and speed of movement and send this information to a high-speed 32-bit
microcomputer, which converts the information into drive signals for the IS lens group. Then the actuator
moves the IS lens group horizontally and vertically thus counteracting the image shake and maintaining the
stable picture. The Shift-IS component is located within the lens groups and is most effective for lower
frequency movements caused by platform vibration or wind effect without increasing the overall size and
weight of the master lens.
