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 have used a D70 for many years - excellent camera. I never missed the video or the next next gimmick - the phone in the camera. I am sure the D90 is excellent as a camera - but as a video machine - that's a bit of a let down. Will the next one come with an MP3 player?
