The Bronx Zoo is a great place.

Michele and I went to the Bronx Zoo the other day armed with a Canon 40D and a Canon 5D Mark II. We used the Canon 70-200 f/2.8 L lens and the Canon 100-400 L lens for everything at the zoo. The 100-400 lens worked better for me as the 5D is a full frame Camera. So in other words the focal length is what the lens says with know crop factor like the 40D. The 40D has a 1.6x crop factor so the 70-200 worked out great for Michele. 200mm on the 40D = 320mm :)

Here is a few shots that I edited so far:

Best,
