Sony A500 has a
12.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz processor. On the other hand, Sony A37 has a
16.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor .
Below you can see the A500 and A37 sensor size comparison.
Sony A500 and Sony A37 have the same 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 Sony A500 has 31% larger pixel area compared to Sony A37, 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. Sony A500 and Sony A37 sensors have been tested by DxO and the results show that A37 has a better overall score of 75, 11 points higher compared to A500's score of 64.
