Not a script, and not in movie mode, just taking photos on the sx200, the zoom works, it might have something to do with the motor Canon uses in that camera. In CHDK on the sx200 you can sort of half push the zoom lever that surrounds the shutter button, and zoom in and out to shoot pictures. If you push all the way side ways, it steps in small increments. Kinda handy, actually. That camera has the print button, and that is the alt button, so you don't have to back out of CHDK, zoom and then press print to get alt again, like I have to with other cameras, or disp on the
sd780, it just works while in alt.
Be kind of neat to add that capability to chdk for all cameras. Maybe the sx200 porting enabled it somehow?
