Sony A3000 has a
20.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features BIONZ processor. On the other hand, Canon M100 has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 7 processor.
Below you can see the A3000 and M100 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A3000 and Canon M100 Cameras
As seen above, Sony A3000 has a 1.1x Larger sensor area than Canon M100. 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.
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 A3000 and Canon M100 sensors have been tested by DxO and the results show that M100 has a better overall score of 79, 1 points higher compared to A3000's score of 78.

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 M100 ,
including hyperfocal distance.
