Back in the 35mm days, I went with a Canon camara and carried around 3 lenses along with the 35-80 that was usually on the camera. I carried rolls of film a flash and extra batteries. It was a pain, but I figured that it was worth it because I probably would never be to those countries again, or see what I was seeing.
Once digital cameras because affordable with really good features, I stuck with Canon and bought their SX10, and then when the SX30 came out, bought that and now I've been using the SX50 for about five years with great results. The SX70 is their newest, bestest model that I'm aware of. I don't believe one brand is significantly better then the others, and Nikon and the other quality name brands are all going to be comparable, so it doesn't really matter what brand you go with.
What I do think is important is that it's a All In One type camera. No changing lenses, or having to carry anything else with you. My battery is rechargeable and good for about 400 pictures. My SD card can hold thousands of pictures. I forget exactly, but my record is 2,600 when I went on a Cruise to ten different countries in the Mediterranean. When in South Africa on Safari, both my PH and I had Swarvoski binoculars. We used my camera as a spotting scope since it has a 50X optical zoom and after spotting the animals with out binoculars, we evaluated them with my camera. It has a flash built in, so there really is no reason to carry anything else with you.
