Well, coner quality isn`t a real issue to justice this type of lens!
They are designed to shoot 3D scenes and not to reproduce flat objects
( = test board). The lens designer often resign to correct the focus
area exact even, to get better over all results.
When you want exact even field (=sharp corners) use a Macro lens.
I have a Zukio 50mm /F1.4 shot of a flat chart with sharp corner`s and a unsharp
center. It was a test for exposure accuracy so I don`t payed too much attention
in focusing. - Maybe it is just a problem with flim eveness?
