I'm going on safari in Africa in a few months and I was pondering the same question. (I have a very old digiatal camera with no optical zoom). From what I read, the best thing is something small as any good guide will get you pretty close to the wildlife and expensive big cameras are more likely to get stolen. I think I'm going to go with a point-and-shoot that has superzoom. The new Nikon Coolpix P90 sounds OK, but, from the pictures I've seen looks a bit bulky to me. I need to make my way to a camera store.
