Sigma Serial Number Date Check
I'm not sure if this has be posted already .
There seems to be an issue with a few sigma lenses and the AF on them .
I've only found out as my new 120 - 400 comes within the problem serial numbers . I've not had any problems but i've only used it a couple of times .
I tempted to contact them to see where I stand if something happens in the future out of warrenty if I don't send it back for checking .
