Sony A350 has a
14.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor . On the other hand, Canon 500D has a
15.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 4 processor.
Below you can see the A350 and 500D sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A350 and Canon 500D Cameras
As seen above, Sony A350 has a 1.1x Larger sensor area than Canon 500D. 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
Both Sony A350 and Canon 500D 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, A350 has scored 65, 2 points higher than 500D.

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 A350
or the
Canon 500D ,
including hyperfocal distance.
