Both Sony a3500 and Canon G7 X MII have 20.0 MP resolution sensors but Sony a3500's sensor is APS-C (23.5 x 15.6 mm ) and Canon G7 X MII's sensor is 1″ (13.2 x 8.8 mm ).
Since Sony a3500's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Canon G7 X MII.
Below you can see the a3500 and G7 X MII sensor size comparison.

As seen above, Sony a3500 has a 3.2x Larger sensor area than Canon G7 X MII. 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 a3500
or the
Canon G7 X MII ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus 1″ ),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
