We already own a C618 (earlier model of this camera) and are buying this as a grad present.
BATTERIES: The way to go with batts is the Panasonic package of charger and batteries, plus an extra package of batts, get it at BJ's. DO NOT USE BATTS WITH ANOTHER MANUFACTURER'S CHARGERS! We suffered faults with Kodak batts and charger, and the Rayovac batts and charger caught fire on our wall plug.
FLASH CARDS: GO with humongous sized memory, you won't be fumbling during that perfect oppportunity. Getting reasonably priced flash cards is best done online, it's easy, AND you don't need an entire flash receptical if you own a laptop, the card holder slides right into the modem slots, easy for travel downloading. We use the laptop, load pics to zips and hard drive (safety) then burn a master CD-R of everything to free up zip space.
FAULTS: The damn on/off button you better watch, putting it into a tight camera case can activtate the on feature, out slides the lens, binding against the case, and scary ratchetting noises ensue. No damage from that yet, but watch it! Darkness is this camera's worst enemy, I haven't got that figured out well enough yet, and the shakes ruin anything with a time exposure. AND THIS BABY TAKES FORRRRRRRRRREVER TO CYCLE SO YOU CAN SHOOT AGAIN, so bring the old motor driven 35MM for those rapid fire pic needs.
We bought two, and that says it all. Plus, nothing like commanility in components.
