Walked over to my neighbors to show him my new toy and he ended up showing me his new toy. He's got the Supra completely torn apart, but he'll have it back together in three weeks or so. I'm gonna shoot some (hopefully) killer shots of his car once it's up and running again. Anyway....the 16-35mm f/2.8 L glass is awesome! I've got to get used to the focusing on the 5D and shoot some real tests later. 16mm. Yes I know the highlights are blown out. 35mm the camera handles the exposure range quite nicely.
