Sensor Size and Resolution Comparison image of Samsung GX-1L and Nikon D3000 Cameras
Samsung GX-1L and Nikon D3000 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 GX-1L
or the
Nikon D3000 ,
including hyperfocal distance.
