"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!"
+2 Internets for that picture, that's just great.
But to be honest, this seems pretty amazing, all this nanotechnology is developing so quickly. It may not be around at a standard consumer level to get this type of stuff done by time I could benefit from it, but my children and their children will definitely be able to live longer, fuller lives due to these types of advances.
