So I am planning a trip to madagascar with my fiancee. This trip has become the impetus for my interest in getting a dSLR. This is going to be a once in a lifetime trip, and I want to have amazing pictures of it.
Anyway, I'm starting to plan my camera and lens purchases now, so that I can buy in a few months, thus giving myself a few months to play around and learn how to take pictures with one of these beasts.
Since we're going to Madagascar, one of my goals is to have some awesome pictures of lemurs. Some are out and about in the day, and others at night. It has occurred to me, however, that having flash go off in the middle of the jungle, at night, will probably be a bad idea. To that end, is there anything I can do to shoot a nocturnal lemur, or will those just be memories, and not pictures.
Relatedly, has anyone gone to madagascar? Any idea if I should go with the 20/30D vis a vis the 350 for durability reasons? Or the 350 over its bigger sibs for weight? Any general wilderness photography advice?
Thanks in advance.

What I think is important is having a pretty wide aperture because it can be very shady in the forest where you're most likely to see lemurs and a off-camera flash (mainly used as a fill during day) because you never know if the animals are going to be heavily backlit or just in a little bit of shade.
