USED. Canon optical solutions to accommodate the increasing number of 16:9/4:3 switchable 2/3” Pro-video cameras.
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)
