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!"
Note: the news release is somehow misleading. the NCSU team just used computer simulations to explain a previous experimental observation from penn state (who published a paper in 2006 in Science and have started a company to commercialize the technology). the NCSU does not develop any new materials. Based on the Penn State information, they have actually doubled the capacitor film performance during the past year to over 30 J/cc.
