12.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Below you can see the A300 and A500 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A300 and Sony A500 Cameras
Sony A300 and Sony A500 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.

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 A300
or the
Sony A500 ,
including hyperfocal distance.
