If you keep the focus distance the same, you will get shallower DOF with APS-C (and narrower FOV).

If you replace non-optical (non-SB) adapter with optical (SB), and do the same, you will get the same DOF and FOV, but gain about a stop in exposure.

Shallower than what?

The comparison is between: 100mm f/2.8 on FF and 100mm f/2.8 on APS-C, without changing focusing distance. The DOF will be shallower on the APS-C set up.
