Sigma 24-70 F/2.8 EX DG HSM Calibration?

[plamen_gb]

As in the title I will be looking to get the lens calibrated as it has terrible back focus at +20 on my 5D MK3 it barely gets corrected and there's still a bit of back focus.

What's the question?

Where can I get it calibrated and any idea how much it costs, thanks.

Phone Sigma directly, they are usually very helpful. They may ask you to send your camera in as well though.

Sigma, about 70 quid last time I checked.
