"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!"
You've got to be kidding me right? Have you ever heard of beta-max. Two formats for the same media cannot co-exist. The only way we'll be paying out our rears is if we have to buy a HDDVD player and a blu-ray player if they both exist forever.
