Assuming you used the middle focus point, you can see the green ball is not in the middle of the frame. The focus point wasn't exactly on it. Also the contrasty part of this ball, the drawing, is even higher in the frame.

The focus point is around that "thing" between the big green ball and other ball and the most contrasty and very close area is where the small balls highlights separating them from the darker background. So, not surprising at all, the camera focused on the most contrasty target almost exactly where the focus point.

No sign at all that there is any problem with the lens from this test. If you have focus issues on a good target where the focus point is directly on that target, that's different. Maybe you can post examples if you do?

If you used a non-center focus point then that's also different.
