A coworker is going on photo safari in South Africa in May and asked me for tips on the trip, as I've done one. One of my primary recommendations was a great low-light camera. The excursions will be dawn and dusk, and many of the animals will be fairly far from the vehicles. Low light sensitivity and long reach are top priorities. I went with a dRebel and a 75-300 and it did fine on reach but was not a spectacular performer in low light, as you'd imagine. I'm totally out of the loop on the state of cameras over the past 3-4 years. She's open to rental or might buy if there's a reasonably priced P&S option.
