Sony DSC-S60 auto focus problem

Archived from groups: rec.photo.digital (More info?)

I was wondering if anyone else has a problem with autofocus in the
movie mode. Both center point and multipoint "bounce" the focus a lot
even if the things that I focused on doesn't move. When I set it to
infinity it seems to do much better but any motion in the scene seems
to make the autofocus change and then try to refocus. It is very
annoying.

I like the camera even though it is a bit bulky and heavy. I have shot
200 pictures and about 1 hour of video.

Another question - I am looking at getting a 1 GB stick - would the
high speed Pro be of any use or will just the Pro be fine for the S60?

Also are there advantages/ disadvantages to getting the Duo?
