Crossover Solutions for 2/3” Pro-video YJ20x8.5B
(Please refer to page 9 for details about Switchable cameras and Crossover technology.)
Canon has developed two affordable optical solutions to accommodate the increasing number of 16:9/4:3
switchable 2/3” Pro-video cameras.
The first solution is the W80Y-85 Crossover Adaptor, a
specially designed compact front mounted wide converter for
the YJ20x8.5B/YJ19x9B, which makes the master lens wider
by a factor of 0.8x. When you use the W80Y-85 on the
YJ20x8.5B/YJ19x9B in the 4:3 mode of a switchable camera,
it performs the Crossover function restoring the tele-side
shifted image to a normal field of view as would be found on
a conventional 4:3 camera. There is no light loss when using
the W80Y-85. (The M.O.D becomes 0.58m)
The second solution is the YJ20x8.5B VRS which has a built-in
“Shrinker”. When the “Shrinker” is in place, the tele-side
shifted image is restored to the normal field of view as would
be found on a conventional 4:3 camera. The VRS “Shrinker”
performs no function in the 16:9 mode while the W80Y-85 is
usable in both the switchable 4:3 mode and the16:9 mode.
