Sensor Size and Resolution Comparison image of Canon A3500 IS and Sony TX30 Cameras
Canon A3500 IS and Sony TX30 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
Canon A3500 IS
or the
Sony TX30 ,
including hyperfocal distance.
