Nikon D80 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor . On the other hand, Fujifilm S5 Pro has a
6.0MP APS-C (23 x 15.5 mm ) sized CCD sensor .
Below you can see the D80 and S5 Pro sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D80 and Fujifilm S5 Pro Cameras
Nikon D80 and Fujifilm S5 Pro 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
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Nikon D80 and Fujifilm S5 Pro sensors have been tested by DxO and the results show that S5 Pro has a better overall score of 65, 4 points higher compared to D80's score of 61.

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
Nikon D80
or the
Fujifilm S5 Pro ,
including hyperfocal distance.
