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!"
Its good to see they are being more proactive to help their customers and acknowledge their problesm… they haven't always been that way… When the 1d Mkiii came out with autofocus issues they denied it for the longest time… Good to see they are making more steps to show their customers that they care about the experience of their cameras. Makes me more confident about my upcoming 5d mk ii purchase
