1. The lens is faulty
2. The camera is faulty
3. The technique is faulty.
I suppose a 4th reason might be a combination of 2 or more of these points.
Isolating each one in turn with structured testing is the only way to sort the problem.
But from that photo, at that f-stop, I can't believe the lens is faulty?
