I see that CHDK enables zoom during video in practically all cameras. However I also read that focus is an issue with many cameras. I see references to strange hacks to enable AF during video in one camera (SX110? You set a button for doing a focus search during video?) while other cameras seem to lose focus while zooming.
So, my question is, for which cameras does CHDK enable zoom during video AND good AF--including during zooms?
Enable means, of course, for cameras that aren't already capable of the above in the first place
