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!"
This is a great idea. Problem, however, is that you have to continuously wear french cuff shirts all the time if you want your data with your at all times. Also, others may wonder why you have the same cufflinks on all the time. Great for practical purposes, but not too great for a fashion statement.
