Here are a few taken with the 70-200 f/4L IS. It is an amazing lens. The Osprey shot was taken hand held, hanging my arm out over the river, out of plain view of the bird. The 60D swivel screen enabled me to frame the shot. The gull was taken hand held at the ocean. The Red Panda was taken at the zoo on a tripod. I love my 70-200 f/2.8L IS II, but there is no chance that I could have gotten the Osprey shot with its weight. The f/4L is staying in my bag.
