Both Fujifilm F800EXR and Sony NEX-5T have 16.0 MP resolution sensors but Fujifilm F800EXR's sensor is 1/2-inch (6.4 x 4.8 mm ) and Sony NEX-5T's sensor is APS-C (23.4 x 15.6 mm ).
Since Sony NEX-5T's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Fujifilm F800EXR.
Below you can see the F800EXR and NEX-5T sensor size comparison.
As seen above, Sony NEX-5T has a 11.9x Larger sensor area than Fujifilm F800EXR. 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
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 F800EXR and Sony NEX-5T sensors have been tested by DxO and the results show that NEX-5T has a better overall score of 78, 37 points higher compared to F800EXR's score of 41.
