AFS by default disallows shooting while not in focus; the other two modes do not. This is why you're experiencing this kind of behavior.
Possible causes as far as I can see:
- Is the switch on the lens set to MF?
- Is the lens broken?
- Try going to MF mode on the lens (not the camera) and focusing. Does the camera show that the image is in-focus and do a double beep? If so, then the lens is likely to blame, or your SDM system is broken somewhere along the line.
