For now it looks to me like bad AF (making the center so unsharp) and field curvature (pulling the borders into focus).



Things are easily checked. Focus manual with live view on the center, and you will know how sharp the lens is at the center. If it is better, you know you have an AF problem with this lens on your camera.



Shoot a horizontal pattern at a 45 or so degree angle wide open. You will get to see the (if any) field curvature.
