Sony a3500 has a
20.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features BIONZ processor. 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.
Sony a3500's sensor provides 6MP more than Sony A380's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the a3500 and A380 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony a3500 and Sony A380 Cameras
Sony a3500 and Sony A380 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 a3500
or the
Sony A380 ,
including hyperfocal distance.
