Move or pan it and you'll see how the field does not move gracefully across.  It almost looks like the correction makes the field opposite of a fish eye lens (which makes sense).Some manufacturers who claim to have a "flat field" apply a little pincushion so that the "rolling ball" is minimized.  Meopta does this well.  Wide... with no "rolling ball"Swarovski is making a design decision that puts emphasis on the static view rather than a panning view.  I'll bet money that they calculated the percent of time a birder or hunter pans vs static view.  I really want to get my hands on a pair and see for myself.  But I gotta think if some say its there in a big way... it could turn a good percentage of people away.Cheers</blockquote>
