Good Fisheye for Nikon D3100?

I found an awesome fish-eye lens on amazon ( http://www.amazon.com/...002LTWDSK/ ) but I realized its the wrong format. Does anyone make a fish-eye at around the same price and quality for DX format Nikon cameras? I don't want a lens attachment, the ring around the photos makes them look unprofessional.

This is a fine inexpensive interchangeable lens and is designed for cameras like your D3100.

You will like it and it is a good alternative to the Nikkor 10.5 mm fisheye, just over $800

What do you mean by the wrong format? Oh, hang on.you're under the assumption that because you have a dx camera you need dx lenses. Funny but untrue. That's a nice, all manual fisheye for a decent price. I've seen it under a lot of names but rokinin is new to me.
