Fujifilm X100 has a
12.0MP APS-C (23.6 x 15.8 mm ) sized CMOS sensor and features EXR processor. On the other hand, Sony NEX-5R has a
16.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Another difference between these two cameras is that Fujifilm X100's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the X100 and NEX-5R sensor size comparison.
Fujifilm X100 and Sony NEX-5R 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 X100 and Sony NEX-5R sensors have been tested by DxO and the results show that NEX-5R has a better overall score of 78, 5 points higher compared to X100's score of 73.
