This is not a calibration problem.
USB Dock here does not help anything.

To f/3,2 AF good. From f/3,5 front focus.
German servise:
"Lens checked; focusing checked; The lens meets Sigma factory standarts. (note, such phenomenon may occur due to the Hyperfocal distance, however, that is no fault of the lens)"
What to do ... ?
