Sensor Size and Resolution Comparison image of Samsung ST700 and Nikon S3100 Cameras
Samsung ST700 and Nikon S3100 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
Samsung ST700
or the
Nikon S3100 ,
including hyperfocal distance.
