Sony A33 has a
14.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz processor. On the other hand, Sony A230 has a
10.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor and features Bionz processor.
Below you can see the A33 and A230 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A33 and Sony A230 Cameras
Sony A33 and Sony A230 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 Sony A33 and Sony A230 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, A33 has scored 70, 7 points higher than A230.

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
Sony A33
or the
Sony A230 ,
including hyperfocal distance.
