Problem with Sigma 70-300 DL Macro

Hi, new user, long time lurker...

Anyways, I picked up a Sigma 70-300 1:4-5.6 DL Macro off of ebay the other week, and I got it today. Cosmetically, speaking, it's well used. I Mounted it on my SF-1n, and it won't autofocus.

Nothing shows up in the viewfinder (as if the lens isn't attached), and when I switch the camera to manual focus mode, nothing shows up in the viewfinder either (focus indicators, and shutter indicator). Interestingly, if I move the aperature away from A, I get shutter indicator, but no focus indicator.

Is the lens busted, autofocus wise?

Any help would be appreciated!
