Sony A380 has a
14.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor and features Bionz processor. On the other hand, Sony A300 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor .
Below you can see the A380 and A300 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A380 and Sony A300 Cameras
Sony A380 and Sony A300 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 (37.14µm 2 vs 26.58µm 2 ) compared to Sony A380, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Sony A380 and Sony A300 sensors have been tested by DxoMark. DxoMark 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. Of the two cameras that we are comparing, A380 has scored 67, 3 points higher than A300.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Sony A380
or the
Sony A300 ,
including hyperfocal distance.
