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!"
Some anti-Apple folks reading these comments :) This ranking system is becoming an indicator of whose fan-boys will read certain articles more. It was good initially when people really ranked idiotic comments down, and something with a valid thought process higher.
