[FONT="]I've recently bought Sigma 18-200mm 1:3.5-6.3 DC OS for my Nikon and noticed that the auto-focus function is not working as well images not coming into focus as seen in the viewfinder.[/FONT]
[FONT="]I bought the sigma USB dock to update the firmware, and the program says the lens is on Version 1.0 without any further updates. Auto-focus and all is still an issue. This was one of the solutions I found online. Another was to downgrade my camera's firmware from 1.01 to 1.00. Could that be a possible solution?[/FONT]
[FONT="]Any help or thoughts on these issues? Thank you[/FONT]
