I have tested  my 75mm perfectly perpendicular to a perfectly vertical board with  a photo test design printed on it. The four corners are perfectly sharp at 1.8.

I would immediatly return and ask another one -not a repair or calibration. I would ask a pure exchange and I would keep pthe number of the lens to vbe sure they are sending it after calibration.

My experience with Canon 3 lenses ; 2 had been returned

My experience with Olympus 5 lenses; 2 had been returned

My experience with Sigma  : 2 lenses : 2 had been returned and one returned twice. After this I have been parfectly happy with the Sigma lenses revised by Sigma and the difference was huge.

Best regards

Bernard
