I'm getting more and more convinced with the Sigma... Where do you bring the lens for calibration? Fixed on the spot? Tks.

You need to make appointment first. Also, you need to leave your camera with lens for them to calibrate. If time permits, I guess you can wait there until the calibration done. Shouldn't take long really.
My suggestion is to wait there while they calibrate for you, because once it's done, you check it on the spot. In case you are not satisfied with the result, tell them directly and most likely they will re-calibrate it again for you until you are satisfied.
For my case, the technician even allowed me into his work area and calibrated in front of me. I am kinda fussy with the sharpness hence he took so long to calibrate for me :sweatsm:
