I was thinking the same exact thing when I saw it only had 50% battery. It didn't drain that quickly last year withroughly the same amount of pics for the same time period. It hasn't gotten knocked or anything. I take good care of my stuff.
The sad thing is, it says for the one year limited warenty to be in effect, you must have the reciept. Which I don't. I did get it from Cabela's. Shouldn't they have record of the sale if I need to return it? They are usually good about returns. Should I go back in and check it more closely, or let it take a few pics with the second card that I put in it today?
