Nikon D200 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor . On the other hand, Sony A350 has a
14.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor .
Below you can see the D200 and A350 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D200 and Sony A350 Cameras
Nikon D200 and Sony A350 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. On the other hand, since Nikon D200 has 39% larger pixel area compared to Sony A350, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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. Nikon D200 and Sony A350 sensors have been tested by DxO and the results show that A350 has a better overall score of 65, 1 points higher compared to D200's score of 64.

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
Nikon D200
or the
Sony A350 ,
including hyperfocal distance.
