But you need a tripod for fine tuning it right?
I think the Tripod will be very important but if you have no other choice you can just hold it.
Maybe find a table to put the camera on and use 2 sec delay to take the picture.
Congrats you got it but The 7K I had made No different, it looked like it got worse trying to fine tune. My local area camera shop gave it a go and seemed to them as the feature didn't not work at all. I sent it to nikon it came back somewhat better but not good enough.I sold it, now either going for the D600 or the D7100. Meantime not a issue at all with my little D3100.
I was thinking about the D600, its using exact same AF system as the D7000 so maybe you might find it as problematic as the D7000.
The D7100 has the D300s AF system so maybe that's a more reliable system.
