Sensor Size and Resolution Comparison image of Nikon S4100 and Samsung TL320 Cameras
Nikon S4100 and Samsung TL320 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 S4100
or the
Samsung TL320 ,
including hyperfocal distance.
