Sony A300 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor . On the other hand, Sony A380 has a
14.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor and features Bionz processor.
Below you can see the A300 and A380 sensor size comparison.
Sony A300 and Sony A380 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 A300 has 39% larger pixel area compared to Sony A380, 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 A300 and Sony A380 sensors have been tested by DxO and the results show that A380 has a better overall score of 67, 3 points higher compared to A300's score of 64.
