I seem to have misplaced my Canon A590 IS and I'm looking for a new camera. I think I have it narrowed down to the Panasonic ZS7, TS2, or Canon SX130.
The Canon is probably going to be very familiar to me and I love having AA batteries since they're readily available and I don't have to deal with LiON and a charger. Of course that adds a little more weight but it's comparable to my 590.
I like the ZS7 and the fact that it's got great ratings, a longer zoom, and GPS. I've never had any luck geotagging images after the fact so this would be a great feature if it works. I'm curious how well the GPS works along the AT. I read a review from a field biologist that it won't get a signal in the forest and if it won't acquire on the trail it's a pointless feature.
Obviously the allure of the TS2 is that it's water-, shock-, and freeze-proof. My biggest concern is that it's the most expensive of the three and I'm afraid of getting screwed. I bought my wife the Olympus 850SW for the same reasons (figured it would be good for when she and our son go to the beach, park, etc) and it takes images that are pure crap. I kept it just because she's ok with the pictures but I guess I have higher standards. I don't want to spend $350 if it's not going to give me good results.
Is anyone familiar with any of these three models? I'd really like to know about image quality and battery life primarily.
