Since you are interested in a 12X lens camera with AA batteries:
Canon S2 IS
Konica Minolta Z3 and Z5
...
..
.
I really like the FZ5, but i was dissapointed to find out that it has a rechargable battery. I'm backpacking this summer and i need to find a camera that will last at least a week and half without having to be plugged in (on AA's or something cheap and easy to get). Thanks for your help!
