I to wouldn't...unless, the 16x9 immage was at the location of the zoom offset.
Like that which was mentioned, on my Sharpvision, when I zoom the image, the top stays in the same place. The bottom and sides move. However, I have lens shift.
However, would this not put a greater burden on the motor and gears. I don't think it was meant to be zoomed in and out all the time?
