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 shaking 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 to counteract the image shake and maintain a 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.
How the Optical Image Stabilizer (Shift-IS) Works.
Both the New DIGISUPER 95 and DIGISUPER 80 lenses come
equipped with the latest version of Canon’s Shift-IS Image Stabilization
technology. This new IS system design reflects experiences gained
worldwide over the past decade that led to deployment of a totally new
sensing system, new correction algorithm, and higher-speed control
loop. The new system extends the frequency range of correction
ensuring high image stability under a wide variety of real-world
perturbations and vibrations encountered in all forms of outside
broadcast coverage. The new algorithm can instantly separate
operational panning and tilting movements from unwanted physical
disturbances.

Canon offers a variety of Mount Converters to be used between a
lens and a camera of different image format sizes. Each converter
will extend the effective angular field of view of the associated lens
according to the Shift Ratio listed below:
*1 SONY's Hot Shoe mount camera, excluding PMW-EX3
*2 1/2" Camera of standard type mount (Panasonic, JVC, Ikegami)
*3 Only applicable to KH10ex / KH16ex / KH21ex
The other 1/2" mount lenses are not available
Note: The converters are to be used with lenses weighing less than 4.4lbs (2.0kg)
