A new item for my wish list

It's no secret that I'm fascinated by cameras and everything having to do with creative photography. I currently own a Nikon D80, with an 18-200mm lens and an SB-600 Speedlight flash... My equipment is not professional but it's definitely above average. I'm lucky to own this kind of equipment and be able to have fun with photos.Today, I decided that I want to buy a Nikon 10.5mm fisheye lens. I think it'd be so much fun to take pictures with a fisheye lens. For those of you that don't know what a fisheye lens is, it is a lens that creates an image with a round effect resembling the shape of the earth. All pictures taken with fisheye lenses look so cool. Here's an example of that kinda of picture as well as an image of the lens I want. The lens it's about $700, so I gotta start saving up to buy it! It's officially on my personal wish list! ;)
