Just wanting to know if anyone has any feedback about these guys. I had to send out my Sigma 70-300mm Lens today because it has something wrong in the focus. It won't focus out all the way. It has a real stiff spot in it. Kinda weird. Never been dropped and it is in a hard case all the time except when I am carrying it in my Soft shoulder bag. Anyway. Just wondering if anyway has had experience with them and their repair dept?
