When taking movies I notice that the camera seems to be continually adjusting, bringing things in and out of focus. I first saw this when I was holding the camera in my hand and taking movies less than a meter away, but today I saw it when tripod mounted, again at a fairly short distance. The subject (a newborn who can't yet move that much, lying on the floor) and the blanket below him come in and out of focus every couple of seconds.

Is anyone else seeing this? Suggestions on what to do to avoid this?

Thanks,

Stephen

So far, every Sony camera I've ever used does this in movie mode. The only thing that will help is setting the focus manually.

The focusing is bad if other people or stuff are in the screen also.

Center AF is the way to go.It will only focus onwhats in the box, not averaging of everything. 0.5-7.0m are as is focus ranges and the side 8 symbol is infinity(for all around focusing). :-)

Unfortunately, this WAS with center autofocus (with the baby in the center), and with no other motion in-frame.

P100 does the same thing. Just set it to manual focus, it's really the only way around it.

Well, that's a good question. I think I've seen the problem in several movies, but they've always been in close range, say, 30-60 cm. And I probably shot at least some of those with macro on; maybe there is a correlation. The specs say that the minimum focal distance is 50 cm, making me think that if I'm closer than that, I need to be in macro mode; correct?

The next time I get a chance I'll try again, making sure I'm at least 50 cm away and not in macro mode.

Thanks,

Stephen

Here's a video I took at a concert with my P100 using 3M manual focus. The sound is distorted because it was so loud and I was right in front of the speakers! http://s32.yousendit.com/d.aspx?id=06ZGMILLBPJUN1NE7FT5R98OJD

Do you have an example of a P200 movie or know a good one out there?
