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
user benefits:

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
