The Canon 400mm f4.5L is a great lens that is fantastic for bird photography and capturing images of birds in flight. The Canon EF400mm f4.5L is an affordable L series lens that is tough, durable and capable of capturing stunning images. If you want a long reach lens that is affordable and gives the most bang for the buck this is the lens to buy.
