Canon 60D has a
18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 4 processor. On the other hand, Pentax K20D has a
15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor .
Below you can see the 60D and K20D sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 60D and Pentax K20D Cameras
Canon 60D and Pentax K20D 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 Canon 60D and Pentax K20D 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, 60D has scored 66, 1 points higher than K20D.

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
Canon 60D
or the
Pentax K20D ,
including hyperfocal distance.
