This Leopard (Panthera pardus) had sought refuge in a tree after being chased aloft into the upper branches by an aggressive pride of lions. The leopard was hissing and spitting, while looking to make good its escape, but the lions maintained their watch. Eventually the spotted cat jumped out of the tree into a nearby thicket and disappeared to safety. The leopard is a nocturnal hunter and described as the quintessential stalk and ambush predator.

Digital Wildlife Photographic Tips
Wildlife work inevitably requires good, long focal lens lengths, but the longer the length the more costly the apparatus. When choosing a zoom lens, prefer a narrower range, say 200-400mm rather than the 100-400mm and use a converter, preferably x1.4 to achieve magnification. Beware of soft images when using a converter… this can be overcome by stopping down (i.e. closing the aperture or in other words increasing the f/stop of the lens, but try not to operate at the outer extreme of the lens.
