You travel to a photographers paradise. You may want to rent a powerful zoom lens for wildlife shots. 300 and 500mm is standard but for quality bird shots you need a steady support such as a tripod or beanbag and a 1000 mm lens. Use dust proof bags to protect your camera. Film is available at camps and lodges but don't get caught short.
Use caution about photographing the military and police or at security conscious areas such as airports. Ask permission before taking pictures of local people and keep in mind that they may charge a fee.
