What are the best tips for professional Safari  photography  ?
-Patience is key, while most animals have predictable migratory patterns, a number of factors can occur to disrupt that. If you are in a vehicle, try driving around and finding other spots. 
-Carry at least 2 cameras, one with a wide angle lens and one with telephoto lens. As you won’t have time to swap out lenses as different animals move around you. 
-Gear can be very heavy, so don’t bring too large a telephoto lens, as shooting from a vehicle can be challenging. 
-Be conscious of your surroundings, don’t be too distracted as you are still in an active environment and animals can react to you.
