Sensor Size and Resolution Comparison image of Nikon S9500 and Sony TX20 Cameras
Nikon S9500 and Sony TX20 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
Nikon S9500
or the
Sony TX20 ,
including hyperfocal distance.
