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 think they actually tested the Pioneer Elite PRO-110FD not the PDP-5010FD. It's a little hard to tell from the article, as it mentions both. But the caption in the picture shows the PRO-110FD vs. the LN-T5281.
