Doesn't look too bad for a 12 mm - some light fall-off, a little moustache distortion, and only a little smearing at the extreme edges. Unfortunately the pictures are shot with an 7R, and they do not provide an aperture value. Does look way way better than the old Sigma 12-24 for FF at 12 mm .
Kind regards, Wim
