If you do go with a camera that uses AA batteries, get the sanyo eneloops. You will want a low discharge battery. You may want to carry 2 extra sets. Also a charger that charges each battery individually. It cost a bit more for the charger, but it will let the batteries live longer for a longer life cycle. Most charge and battery sets give you a charger that needs to recharge in pair, they are not as good. Get the battery and charge separately.
Not sure you want to experiment with NIZC, the higher voltage may not be good for the K-x. Since there were earlier issues with nimh that they needed to address with the a firmware release.
