Pentax ist DL2 has a
6.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor . On the other hand, Pentax K10D has a
10.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor .
Below you can see the ist DL2 and K10D sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax ist DL2 and Pentax K10D Cameras
Pentax ist DL2 and Pentax K10D have the same sensor sizes so they will provide same level of control over the depth of field when used with 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. Pentax ist DL2 and Pentax K10D sensors have been tested by DxO and the results show that K10D has a better overall score of 66, 1 points higher compared to ist DL2's score of 65.

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 ist DL2
or the
Pentax K10D ,
including hyperfocal distance.
