Canon 50D has a
15.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 4 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.
Below you can see the 50D and NEX-5R sensor size comparison.
Canon 50D 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. Canon 50D and Sony NEX-5R sensors have been tested by DxO and the results show that NEX-5R has a better overall score of 78, 15 points higher compared to 50D's score of 63.
