Hi All Csers,
I'm using sigma 70-300mm APO DG macro (canon mount) for only like 4 months..
I wonder if anyone had encounter the zoom ring to be loose and tend to extend to 300mm when at down position..
My friend had a similiar lens (nikon mount) and bought at the same time but his doesn't have the problem..
So i would like to find out does anyone else had encounter such problem..
Thanks
