Web1. All lenses show some degree of distorsion, but I suppose that you mean the difference between regular lenses and fish-eye lenses. The widest non-fish-eye full-frame lens that I know of is the Sigma 12-24mm 1:4,5-5.6 DG HSM. A focal length of 12mm on a 36mm sensor gives you an angle of view of 112,6°. Circular fisheye is only one of many possible distortion functions. Two disadvantages of circular distortion are that it compresses (rather than magnifies) the area near the …
