Not very good of the Coot. I must admit it, my camera or lens have bitten the earth, no ........use at all. I had to do with 30D, and the lens......I have not an other. Now I purchased one Canon EOS 7D, so I can carry that until it falls ill. And lens, well I was lucky, there was Brian (http://www.brianswildlifephotos.blogspot.com/) who was willing to lend me 300mm. Really good. Bravo Brian.
