Press the power button and you'd be forgiven for thinking the batteries (normal AA - you'll want to buy some rechargeables) are done. Add in a marked shutter lag, s-l-o-w zoom and 5sec to write a photo to memory, as well as about 3sec to change flash settings and you'll be as frustrated as hell if you see a quick photo op. Oh, and any flash format changes are lost when you turn the camera off.
