At Mt Wilson's Cosmic Cafe, the Hummingbirds feed, fight and play. Really fun to watch worth buying lunch just for the show. I just had to put the 7D to the test. Forgive the soft focus, the birds are FAST!
This is a collage of one birds approach to the feeder. I had the camera in manual focus, high ISO, and a very fast shutter, a 4/000th of a second. The camera was set to shoot at it's maximum eight frames per second. The collage was edited and assembled in Picasa 3.8
