A friend of ours, SGM Rock, let us borrow his fisheye lens.
Greg had some fun with it. (He also added some other effects, fear not, we have not cloned Adam. The world can only handle ONE!)
A fisheye is something I've been wanting for a while...Although I wouldn't use it for portrairture, it's a fun lens. Not as practical as say, a 12-60mm, but it's FUN....I can't wait to get some fun pictures at one of the weddings that I am shooting next month.
