This tiger lives in a very large exhibit at the Wild Animal Park.
He was so far away that he was almost impossible to see, unless
he moved, or was pointed out by someone else who spotted him before.
This is a 100% pixel crop of the original 8 megapixel picture.
Had I wanted to get this view full frame on a 35 mm camera, I would
have needed to use a lens of greater than 1500 mm focal length
(200mm times 1.6 crop factor of the 20D sensor times 3500/720 pixel crop)!
