Fujifilm S3 Pro has a
6.0MP APS-C (23 x 15.5 mm ) sized CCD sensor . On the other hand, Nikon D300S has a
12.0MP APS-C (23.6 x 15.8 mm ) sized CMOS sensor and features Expeed processor.
Nikon D300S's sensor provides 6MP more than Fujifilm S3 Pro's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the S3 Pro and D300S sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm S3 Pro and Nikon D300S Cameras
Fujifilm S3 Pro and Nikon D300S 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
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. Fujifilm S3 Pro and Nikon D300S sensors have been tested by DxO and the results show that D300S has a better overall score of 70, 10 points higher compared to S3 Pro's score of 60.

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
Fujifilm S3 Pro
or the
Nikon D300S ,
including hyperfocal distance.
