Canon EF 8-15mm f/4L Fisheye USM
Make room in tight spaces: It's a fisheye lens at 8mm. It's an extreme wide angle lens at 15mm. And it zooms. This pioneering triple threat L Series lens is just the thing for shooting in cramped quarters, capturing that expansive landscape, or fitting all of your family into a fun (and funky) reunion portrait. On a full-frame sensor like the one in Canon's EOS 5D Mark II , it gives you the opportunity for either circular or full-frame fisheye images with a full 180 degree field-of-view.
