Sending my Sigma 30 f/1.4 for AF Data Adjustment?
Jul 19, 2011

I did a search and it seems like there have not been anything new on this topic. A handful of posts saying they have sent it to New York.

Just wondering whether anyone else has had some recent experience and can share it here.. such as the time it took and how effective it was. My copy is front focusing and at f/1.4 it renders it quite useless..

Thanks!
