p.1 #1 · Anyone had Sigma correct back-focusing on 50 1.4?

Has anyone sent their 50 1.4 along with their camera to Sigma to have it adjusted to focus properly? I'd like to know if they can and will do it, and whether they charge anything, and if it comes back working correctly.

My Sigma 50 was severely back focused and I sent my 5D to canon without any lenses and they corrected back focus on the camera to their spec in house lens. When I got it back my 85L was dead on and the Sigma 50 1.4 was a bit front focused.
