Canon Digital Slr Fisheye Lens
Question about Canon SLR cameras …?

I'm getting the Canon EOS Rebel XS and I want a fisheye lens and I wonder how everything what works. Could I use this: If so http://www.amazon.com/Opteka-Panoramic-Fisheye-Digital-Cameras/dp/B000TQPTTM/ref=sr_1_1?ie=UTF8&s=electronics&qid=1259279181&sr=8-1 How exactly what you put the lens on? Only someone explain this to me haha, thanks:)

First, a great camcorder. Second how lenses are attached to the camera are sliding into a ring and turning left or right (depending on how you're looking at the camera). Once you hear a click then it will mean the lens is locked in the camera and you can begin to capture the works of art;)
