Nikon Df has a
16.0MP Full frame (36 x 23.9 mm ) sized CMOS sensor and features Expeed 3 processor. On the other hand, Nikon D700 has a
12.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Expeed processor.
Below you can see the Df and D700 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon Df and Nikon D700 Cameras
Nikon Df and Nikon D700 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
DxOMark Sensor Scores
Both Nikon Df and Nikon D700 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the

or the
Nikon D700 ,
including hyperfocal distance.
