I own the Sigma 10-20mm F4.0 – F.56 EX DC HSM wide angle lens and it is awesome. “Wide Angle” really doesn’t do it justice. The angle of view is so wide (104 degrees) I’ve accidentally actually got my feet in the frame. This lens’ angle of view is 180 degrees. You’ll be able to photograph stuff behind you with this thing.
