Hi there. I just got back from a week and a half in Costa Rica, most of which was not conducive to Nikon D3200 shooting, because it was wet and involved kayaking, rafting and rain.
My D3200 use was also limited a good bit by the fact that my battery charger died fairly early in the trip. Fortunately, because I had two batteries and both were always kept topped up, and because much of the trip I used only my waterproof pocket camera, I made it through the trip, economizing on battery use with VR off and back button focus. By the last day AF was getting spotty. I just wanted to emphasize how important it is to have at least one fresh fully charged battery in reserve, and if you're going far and deep away from convenient facilities, maybe even an extra charger!
Bummed is a mild term for the feeling I got when that charger went dead! When you need VR and AF to catch a flying quetzal, seeing that battery icon go black is no fun.
