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 own both the Grundig FR-200 and the Sony ICF-B01, there is NO comparison! The Grundig "might" last 10 minutes, but the Sony will last hours with same amount of cranking! I cranked the Sony last night @11pm for ~ 1-2 mins and it was still running when I woke up this morning!
