Just like using the center of the D800's sensor in DX crop mode. Try this potter:

Go to DOFMaster. Input 420mm on a D7000 @ f5.6 at 30'. Now input 300mm on an Olympus micro 4/3rs @ f4 at 30'. You may see what I mean.

Again, subject distance is not the same if you keep same framing. See pics I posted above. If you not keep the same framing....then it's no different than cropping in post so no change in DOF.

Note...you can't use the online calculator in this case as film format and circle of confusion are no longer a constant.
