Let the hive mind of Engadget get that for you.
"We need a digital camera that can be switched on and fire off that first shot fast. It's not a commonly tracked statistic on any review site, and nobody seems to have this information for every camera. We were hoping other readers could inform us as to what small digital cameras can fire off their first pics in under a second (ideally under half a second). It needs to be small, but mostly, just really quick in operation. Thanks!"
I'm starting to do this myself, although my local theatre is not helping things. They used to bring the good movies in, but now they have changed managers. The new manager doesn't have a clue, we think the owner is trying to sell this theatre. I actually had to drive 60 miles to catch two good movies this year. I'm mostly waiting for the dvd to come out these days.
