Eyelight Plays with Depth of Field - Part 8: The shift in the near and the far.

These are charts depicting total DOF and the shift between the DOF in front of the focal point and the DOF in rear of the focal point. The calculations use the CoC (circle of confusion) of a DX sensor, though the trend appears similar for FX. Each chart uses a focus distance of 1 meter, the focal length listed above it and progresses thru the apertures in full f-stops.

Caution: I'm just playing with some calculations and charting. If you really want to know and be certain, confirm this stuff with your experience, either already or later.
