or could someone please help me ask?
Item: Sigma 30mm f1.4 EX DC HSM
Purchase date: 21/11/2008 (as per receipt)
Problem: slight back-focusing (~2mm)
I have posted some of the photos that I have taken yesterday for the Red Bull X fighter Motorcross. They can be found at here.

give them a visit, call before going. bring along your body to show how bad is the f/b focus issue. since yours is a grey, i guess the lens is not under warranty, so u may need to pay the charges. but u can try getting ard it by sending emails to the top management of Sigma in Japan, cc those in Singapore.
