Up for sale/trade is a 400 2.8 non IS. I traded for this lens a few months ago and it is just too heavy for the purposes I am using it for. The link to the original post that I picked it up from is below and has pictures both of the lens and from it. If you'd like to see more pictures from the lens I can e-mail them to you. As you see in the photos it is well used but functions perfect. The two things I can think of besides aesthetics that are wrong with it: 1. The hood doesn't stay on very well. 2. There are 2 small nicks on the front lens that become visible against a plain background at around F11 or so (I haven't really tested as I and I imagine most people who would purchase this lens would use it at 2.8 or near it).
Will P, I did PM you back...I had a lot of interest in it. Mike and a few others had expressed interest earlier on so I was waiting to hear back from them. Thanks for the interest.
