My Canon 40D arrived today. I'll post some pictures when I figure out how to use this thing. This is my first dslr, so give me a little time. It came with the 17-85 IS lens. Any thoughts on this lens? I plan on purchasing a good telephoto lens in the future. Any suggestions? I will use it for photos of my son as he grows (sports, playing, etc.) and I would like to be able to get some good wildlife photos. Any info would be greatly appreciated. Thanks!
