I have also posted this on Fred Miranda's forum. Anyway, the lens is the 70-200L of the f/4 variety. I bought it about a month ago, and have used it sporadically, but find that I need a faster lens for my available light shooting. So, I am looking to sell this one. Everything is as new in original packaging, including blank cards etc. Make me an offer.

P.S I have been using it on a 10D body and it is tack sharp.
