Most of the WA converters available really are
"fisheye"-type, but vary in the angle of view shown
(the .66X Raynox HD6600-58 is the only one I've
seen that isn't), but for panning/tilting/people-at-edges,
this has advantages over a "low-distortion" WA (which
actually looks more "distorted" when showing camera
rotations and when showing rounded objects [like
people...] near the edges). For more on this, see:
