Lloyd chambers has tested it and finds that there is indeed peripheral focus shift -- i.e. more edge shift than centre shift (another way of thinking of that is that there is field curvature which gets worse as you stop down) And sadly the initial thought that it is compensated in FW seems not to be true.
Not that uncommon in good UW zooms - the Nikon 14-24 has it just as bad according to Lloyd.
Other than that, though, he finds the lens to be exceptional - as good or better as any uw zoom, and very flat field wide open.
BTW his tests seem in conformity with DXOs
