If photography is your thing, some of the operators specialise in catering to the photographer. Some photographic safaris provide bean bags and dust covers for your camera bags. Parks such as South Luangwa National Park have great photographic hides where you can sit comfortably and wait as long as it takes for that perfect shot.
Tips:a good zoom lens, 200mm or longer will prove very useful on safari. Be sure to carry your equipment in a well-padded heat and dust-proof case.
