Best camera lenses for wild elephant photography in Minneriya

A 70-200mm lens is actually perfect for Minneriya. During the "Gathering" (August/September), the elephants congregate on the open grass plains near the reservoir. The jeeps can get relatively close (safely), and the elephants often walk right past the vehicles. A 600mm lens is often too tight for herd shots. Bring a wide-angle lens as well for environmental landscape shots of the massive herds.
