Canon 350D has a
8.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor . On the other hand, Pentax ist DL2 has a
6.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor .
Below you can see the 350D and ist DL2 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 350D and Pentax ist DL2 Cameras
As seen above, Pentax ist DL2 has a 1.1x Larger sensor area than Canon 350D. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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. Canon 350D and Pentax ist DL2 sensors have been tested by DxO and the results show that ist DL2 has a better overall score of 65, 5 points higher compared to 350D's score of 60.

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 350D
or the
Pentax ist DL2 ,
including hyperfocal distance.
