Special Optical Elements
Canon has always made an effort to research special optical elements
since our beginnings in this industry with the goal of minimizing
chromatic aberration. These efforts have included an artificial element,
"Fluorite", with extraordinary dispersion characteristics and the newly
developed "Hi-UD" (high index ultra low dispersion) glass. Canon has
succeeded in the practical use of special elements along with advanced
design techniques like "separate achromatism". Canon TV zoom lenses
carry a "Green Ring" on the focus barrel, a symbol of our high quality.
Canon has developed a break through in optical design technology
known as the "Power Optical System" whose heart is the "X-Element".
By using the "X-Element" to its maximum power in the specially
designed optical layout, higher specifications and quality can be
achieved in smaller and lighter lenses. The lenses designed using the
"Power Optical System" are known as the "XS-series".

Aberration Correction for HDTV Lenses
The pixel size is about half in the HDTV system,
and therefore the spread of a point image caused
by a spherical aberration, coma, etc. should be
diminished to about half. Even if the image is
slightly out of focus, MTF is greatly influenced.
The graph 1 shows how MTF varies when the
focus changes. Canon HDxs series lenses employ
the HD version of the Power Optical System,
which incorporates the X-Element. HDxs greatly
contributes to correcting and minimizing these
aberrations at the same time, maintaining high
MTF throughout the edge of the picture (graph 2).

in either direction.

An angle of view can be preset in either of two memories
and the lens will zoom to that position by pushing a simple
button. During a performance, framing preset will reproduce
the zoom position decided upon at the rehearsal. It's easy to
repeat the same zoom as often as you like at the highest
speed or in a preset zoom speed.

Optical Shift Image Stabilizer (Shift-IS)
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 group 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.
