D7000 and D3200 (or D5100) sharing lenses

My current second camera is GH2. It is a very nice camera, however two sets of different lenses, two sets of different batteries and chargers and two different ergonomics. I am thinking to sell GH2 (still within 1st year warranty + extra two years) and get D5100 or D3200.

My Nikon D7000 lenses are AF fine tuned. Adding a new not AF tunable Nikon body I think of only one option - to send the lenses and the new body to Nikon and then readjust the the D7000.

However, may the D3200 (D5100) would not need AF to be fine tuned.

My question to those who has D7000 and D5100 or D3200 (D3100).
What is your experience?
Thank you.
