Fujifilm S5 Pro has a
6.0MP APS-C (23 x 15.5 mm ) sized CCD sensor . On the other hand, Pentax K-m has a
10.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor .
Below you can see the S5 Pro and K-m sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm S5 Pro and Pentax K-m Cameras
Fujifilm S5 Pro and Pentax K-m 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 Fujifilm S5 Pro and Pentax K-m 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. Of the two cameras that we are comparing, S5 Pro has scored 65, 1 points higher than K-m.

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
Fujifilm S5 Pro
or the
Pentax K-m ,
including hyperfocal distance.
