The majority of my safari photography is at ground level. However, once in a while I take a group that;s looking to expand their creativity with some aerial work. Typically we take a small single prop and fly over several areas where the landscape and wildlife will provide some interesting compositions and scenes.
In order not to disrupt the wildlife I use anything from a 200 to a 400mm lens keeping the iso around 400 f3.2- 5.6 and shutter at a minimum of 1/2000.
Wider landscape shots are taken on a second body with a 60mm. I rarely use a wide angle lens except for cityscapes as it pushes ground objects much further away. The difficult part is predicting the view as the time frame to capture the shot is just a few seconds, then the angle and viewpoint is gone as you fly past the subject. Alot of time is spent looking head and keeping the camera at the right position ready to shoot.
