Joe and Mary Ann McDonald organize Africa photo safaris geared for serious photography. However, they only do 2 or 3 of these a year.
I have been to Africa with Joe and Mary Ann several times and they run a great trip. They handle all the details and make sure the trip runs smoothly. This is no small feat, just remember TIA - This Is Africa. Things work differently over there. Short a vehicle, crowd more people in.
A photography safari is different than a tourist safari. Meals are nice but not essential. A tourist would get board watching a den hoping a mother cat would return for her cubs. ... Plus in a tourist safari everyone gets their own window, in a photo safari everyone gets their own row.
Just a few thoughts.
