As a wildlife photography enthusiast you will want great pictures of the Big Five, all other amazing animals and maybe also great landscape shots. Your perfect African photographic safari would be going home with the perfect picture.
In order to get that, your safari should be planned carefully. Choose safari destinations that offer excellent Big Five sightings. Go rather for private game reserves or concessions than for game drives in public parts of national parks. Consider a private vehicle to have enough space for your photography and freedom of movement. Choose your time of travel carefully and ask for an experienced guide.
Last but not least the accommodation should offer facilities to charge your photographic devices preferably in your room and if the lodge/camp has Wi-Fi that would be nice, in case you want to share your images immediately.
All that set, you will achieve your goal and come home with the perfect picture.
