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!"
Guys.... I think this is a great invention. I know this post is outdated by now but you guys should seriosuly check out the website now. www.hymini.com. They launched the new addition (miniSOLAR), it's bassically a solar panel(s) that can be hooked onto the hymini and charge power to the hymini. It's extremely efficient! I bought one set for myself three months ago, been loving it like no other!
