I observed three red fox kits for about an hour one early morning. While mother and the kits were aware of our presence, the kits continued to romp around, paying little attention to us. I captured this intimate moment of mom and one of the kits before it dashed away to chase its other siblings once again. I caught this image with the equivalent of a 630mm lens fitted to a tripod-mounted camera (300mm lens with a 1.4 teleconverter on a cropped sensor). You don't always need the fastest and most expensive lenses. I find this combination very flexible albeit a little slower than the fastest lenses.
