24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 8 processor.
Below you can see the A3000 and M200 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A3000 and Canon M200 Cameras
As seen above, Sony A3000 has a 1.1x Larger sensor area than Canon M200. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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 A3000
or the
Canon M200 ,
including hyperfocal distance.
