Something wrong with my autofocus

[reconova]

I've got a Sigma SA-5, using the 35-105mm lens.

when i go to AF mode and focus, the lens makes the usual robotic sound, but the lens don't focus??

anyone got any idea?? camera or lens spoil?

Still can manual focus.

Which one spoil? the body or the lens?

probably the lens if tt is the only lens tt give this prob...if more than one lens on the body then body spoil lo..
