If you want near instant response, then a digital SLR would be the way to go. Take a look at Canon Xti/400D, Nikon D40/D40x, and similar models from Olympus, Pentax, and Sony..
You will get better response times from your P&S type digital camera, if you prefocus: press the shutter release half way down to force the camera to auto-focus, then shoot when the moment is right. A digital SLR will still give you a much shorter shutter lag than a prefocused P&S..

Actually the opposite is true...
Casio P&S cameras have a video mode called Past Movie that actually starts capturing video 5 seconds before you press the button. You could use that and grab a still from it. Too bad there isn't a still image version of the feature (I think)...

Agree with this part..

Dis-agree very much with this part. For the fastest response time I'll take my pre-focused P&S (a Fuji F20) over my un-focused DSLR (a Canon 400D)..

Fuji F30 (no F20 review) Pre-focused 0.018 secondshttp://www.imaging-resource.com/PRODS/F30/F30A6.HTM.
Canon 400D Pre-focused 0.105 seconds, Full shutter press 0.20 seconds,http://www.imaging-resource.com/PRODS/XTI/XTIA6.HTM.
Canon EOS-1Ds Mark II Pre-focused 0.052 secondshttp://www.imaging-resource.com/PRODS/EOS1DS2/1DS2A10.HTM.
Sony 717: Even the 5 year old Sony 717 (pre-focused 0.120 seconds) doesn't lag far behind the Canon 400Dhttp://www.imaging-resource.com/PRODS/F717/F71A7.HTM.

I agree that there are some P&S out there with very short shutter lags; some of the Sonys have claims of less than 10 ms. And you would kind of hope that with an electronic shutter and without the need to flip the mirror short lag times should be possible. However, shutter lag times for P&S cameras vary enormously and many are still very slow. DSLR timings are more consistent and I think on average shorter than P&S times..
For action shots I would take my not so fast Canon 5D over my supposedly faster F31fd any day..
Not strictly correct, most P&S cameras PREFOCUSSED are much quicker (< 20 mS) than DSLRs because they don't have to move the mirror. Moving the mirror takes between 60 and 100 mS depending on the make and spec of the camera..
Fast P&S camera (prefocussed) are Sony, Panasonic, Fuji, Casio. Canons are probably 'hobbled' somewhat (prefocussed time ~ 80mS) so as to make their DSLRs look better..
Look at this site for comprehensive timing tests:.
Thanks, everyone, for the great tips. It's possible my Optio has a video mode (I really need to read that manual!), and if so that's the way to go. The need to pre-focus is part of the problem, if not the whole problem...
Casio Ex-V7, Fuji F40fd..
I want to be able to take instantaneous candid photos - for example,children playing, where the pose will change by the time my currentdigital camera (a Pentax Optio M10) actually lets me take the shot.The camera takes a while to focus (I realize it's an automaticcamera), and then the photo shows up in the viewfinder (althoughpossibly that's a default that can be changed - the real problem isthe length of time it takes before I can actually take the photo). Isthere any such thing as an instantaneous-click digital camera, or doI have to go back to my 35 mm film camera?.
