All of us play, but my wife is the best by far (two music degrees). I did a few other quick tests outside...there's definitely a bit of field curvature, but not so bad it can't be overcome. Definitely worth stopping down to f/8 or so if shooting with detail near the edges that is near infinity (and focus to the hard stop).
It also is good enough at the edges that a full defish actually works pretty well...maintaining fairly good sharpness at the edges (though this results in a much lower total resolution...I'm using PerspectiveEfex for the defishing, and after doing so, I end up with around a 20-22 megapixel image (depending on the horizontal/vertical adjustment), but that's still plenty good enough for most uses.)
here's that test shot defished, then corrected for perspective distortion (since I had the camera tilted down a bit). This is still exceptionally wide, and around 10-11mm rectilinear FOV by my estimats.
