Default Quick autofocus?

About a week ago, I bought an Olympus C-3020 off ebaY. 90% of the time, the camera is fine but there is one thing that is aggrevating. The autofocus.

I guess the autofocus works fine, it just seems to take so long that if I want a candid snap, the moment is gone before the picture is taken.

Any suggestions? Is there a setting to change? New camera? What?

Push the shutter release halfway in anticipation of the shot. That pre-focuses and the shutter delay is much shorter. http://www.imaging-resource.com/PRODS/C3020/C32A7.HTM

You won't do better with another camera. That one is very fast in comparison.

I have a very old 1MP HP C200 camera with an extremely slow auto-focus. With that cam there is an option to set it into "focus free" mode, i.e. the lens reverts to a kind of disposable camera type setting. The image isn't quite as sharp close in or further out then, but it is loads faster taking a shot.

The fastest 'autofocus' is manual focus mode. Most compact cameras will offer a considerable depth of field at wide angle, so you can choose say 2m to infinity. However, use zoom- and focus needs to be correct as depth of field reduces fast. VOX

If you look at Dave’s speed tests, his Oly 3020 has a 0.54 sec shutter delay with manual focus and 0.138 with pre-focus. So it is over 3 times as fast with pre-focus than with manual. That is a bit extreme, but most cameras seem to be a little faster with pre-focus than they are with manual focus.

This sounds interesting. Where do I find Dave's speed tests?
