This is the lens you will most often see on the end of my Diana F+.
Yes, you can get real close and get amazingly funny and distorted shots of people you love and, if you dare, animals. But I prefer to step back and take as much in as possible.
I like to use it with medium format film to get the whole circular feel of the Fisheye.
But even more, I love the way it looks with 35mm film, sprockets exposed!
