Canon is proud to introduce the
YJ20x8.5B, which has emerged from Canon's top
selling YJ19x9B, also known as the Pro-Video Industry Standard
Lens.
The YJ20x8.5B tops many Pro-Video standard lenses by offering the
widest focal
length (8.5mm), the highest zoom ratio (20x), and the fastest zoom
speed
(1.2 sec from wide end to tele end). In addition to having Canon's
innovative
Internal Focus (IF) Technology and exclusive Shuttle Shot Function,
its new ergonomically designed drive unit accounts for its ideal
balance and comfort.
IF
Technology
Pro-Video camera people can take advantage of Canon's breakthrough
technology
that broadcasters have enjoyed for years-Internal Focus
(IF).
Internal Focus technology was pioneered by Canon and first
introduced into their Broadcast ENG lenses.
It has since become the industry-standard. Internal Focus is a
system where the
front end of the lens remains stationary and does not rotate.
Only internal elements move when focusing.
Internal Focus enhances optical performance and provides several

IF improves chromatic aberrations, thus increasing
resolution.
IF is not sensitive to change in object distances.
IF decreases flare by use of square food.
IF enables a higher level of creative filter work.
Even heavy optical accessories attached at the end of the Lens does
not affect the focusing operation.
New Ergonomic Drive
Unit
The new ergonomically designed Drive
Unit achieves an ideal balance and comfort by having it tilt to
an
angle. In addition, the size of the unit has been minimized to
comfortably fit in the palm of the hand. Overall,
it improves the feeling of unity between the user and the
lens.
Shuttle Shot
Switch
The Shuttle Shot function ON/OFF
switch can also be allocated to either the VTR or RET switches by
means
of a DIP switch.
Ribbed
Surface
The ribbed surface on the bottom of
the Drive Unit provides better handling control.
Grip
Support
Allows a user to securely grip the
Drive Unit without pressing on the VTR or Shuttle Shot
