I think if something is really wrong with a lens, it doesn't take a 61MP sensor to notice this... (remembering how my decentered Canon 16-35mm f/2.8 L II was acting as a non-adjustable tilt lens even on an 8MP APS-H body... though that was the result of impact against terrain).

Anyway, it's always entertaining to read a review of something odd, like a macro, a TS lens, a fisheye... once in a while.
