Sensor Size and Resolution Comparison image of Nikon D200 and Nikon D300 Cameras
Nikon D200 and Nikon D300 have 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 21% larger pixel area compared to Nikon D300, 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 Nikon D300 sensors have been tested by DxO and the results show that D300 has a better overall score of 67, 3 points higher compared to D200's score of 64.
