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!"
The HF10 specs sound great - except - for those of us who frequently prefer to use an eyepiece for recording. The new flash memory Canon cameras have none!
I have an HG 10, which has a great widescreen eyepiece. I'll keep that.
