Pentax K10D has a
10.0MP APS-C (23.5 x 15.7 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 K10D and S5 Pro sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax K10D and Fujifilm S5 Pro Cameras
Pentax K10D 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
Both Pentax K10D and Fujifilm S5 Pro 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, K10D has scored 66, 1 points higher than S5 Pro.

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
Pentax K10D
or the
Fujifilm S5 Pro ,
including hyperfocal distance.
