Em and Lisa - my camera is just a point and shoot Nikon COOLPX L610. I don't even know what the zoom is. The deer in the previous photo was right next the path that I was walking on, maybe 15 feet away. I hit the zoom slightly. The deer around the lake are used to people and you can get pretty close to them.
Ranae - I think the deer's head is a normal size and maybe just looks small because of the angle.
