Similar cameras with similar capacity batteries are running 700-1200 exposures per charge these days, no reason the K10D will be any different. (For someone coming from film cameras, that's 20-35 rolls of 36 exposure film per charge... :-)
The body will come with one battery and a charger. The AC adapter is for tethered, mains-powered use in a studio or similar and is thus optional. Batteries like this normally take 1-3 hours to charge from fully exhausted to full capacity. I'll order at least one spare battery when I order mine, and then I'll wait to see if I actually need a third. For a month long travel expedition, presuming I have access to mains power most evenings at least, I'd want two spares. If you're going into the boonies and will not have regular access to mains power, invest in an inexpensive DC->AC power inverter with about 20% more amperage capacity than the charger needs so you can charge batteries from a 12V automobile power source, and maybe add another spare battery or two. (For the *ist DS, with CRV3 Lithium disposables, a set will run about 1200-1300 exposures. Five sets, not a case, would make 6000 exposures or the equivalent of 130 rolls of film or so. That would do me for far longer than a month's worth of shooting.) Godfrey On Sep 15, 2006, at 7:10 PM, Bill Lawlor wrote: > I am very interested in buying a K10D asap.
