And when I use it on sports or Dark it tells me there is a connection problem with the lens to Camera What can I do

Hi,
The original DL lens was designed for non-digital application and Sigma released the DG version that was optimized for digital bodies. That said, the lens should still function to a certain extent on both and function normally on your wet film SLR.
My first suggestion would be to check the contacts on the lens and camera. Give them a good clean with a pencil eraser being careful that nothing goes inside the camera body whilst doing it.
If this fails to make any difference than the next thing would be to try the lens on a different body. The fact that the lens isn't performing correctly on two bodies leads me to think it is a lens problem but it's good to eliminate the bodies.
If this fails to make any difference then the last thing is to get it professionally looked at. Most local camera shops would do this for you. Be wary though that repair may cost more than the lens and it might be the right time to upgrade to a nice new lens to get the most out of that new DSLR!
Hope this helps, if it does please rate my help.
Thanks
