I've got a Canon 200 2.8L mk.I prime lens for trade or sale. It is a great lens and takes great photos. I've been using it on my 5dii and have been very happy with it. I simply don;t have the time I used to to take photos. I'd like to get $500 cash for it or will gladly trade for gun related stuff. I'm interested in Glocks and ARs and accessories for both mostly, but feel free to make me offers.
