Sensor Size and Resolution Comparison image of Nikon D80 and Nikon D300S Cameras
Nikon D80 and Nikon D300S 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 D80 has 21% larger pixel area compared to Nikon D300S, 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 D80 and Nikon D300S sensors have been tested by DxO and the results show that D300S has a better overall score of 70, 9 points higher compared to D80's score of 61.
