I tried today after receiving my Neewer labelled 'Shoot' MC-DC2 remote switch from Amazon U. K. (£2.44) and like it very much. I pushed it to lock position after the 'pre-focus' and 'swerve lens away' procedures.
In addition, you must assign the AE-L / AF-L button to AF-ON, disabling the shutter release buttons (including remote MC-DC2) to initiate auto focus (AF).
Next, to let your D7000 work 'auto-firing', you must use AF-C, and set it to release on 'Focus' rather than 'Release', on page 208 of the D7000 English Instruction Manual (a1: AF-C Priority Selection).
If you use AF-S, it will fire regardless of your object is in focus or not, because the camera will only consider for once, the object appear in focusing point (tiny square), seen in the viewfinder is in focus or not.
Whereas in AF-C, the camera will continually considering your object appearing in the tiny square (focusing point) is in focus or not. As a result, when your object is not in focus, it will stop firing. D7000 will auto-fire again when object is in focus.
The D7000 manual does not give you this instructions, but fellow Nikonians help each other to figure out this trick.
