It is not the same situation as with the nex7. The nex7 has a design fault, smearing corners with certain lenses and producing discolouration. The 5Ds® just shows the limits of the lens, and the effect is just exaggerated by PZ's sharpening which on other cameras makes the corners look better, so the difference with the 5Ds seems larger.
