FOR SALE- Sigma 8mm F3.5 EX DG Fisheye Lens, Nikon fit !

I am reluctantly selling a Sigma 8mm F3.5 Fisheye Lens, to fit Nikon, in excellent condition. I have only used this lens a couple of times, but the majority of the time it has remained in its box unused. It is a lovely little lens and retails at 620 brand new. This is in great condition and comes with its original packaging. This lens can be used on any Nikon camera, and on a full frame DSLR or 35mm Film SLR, it can take pictures with an angle of view of 180°. Brilliant versatile lens and can be used for all types of photography. This link gives an example of some of the photographs you can get with a Fisheye lens. http://www.flickr.com/groups/fisheyeqio/pool/
