Nikon 1 J4 has a
18.0MP 1' (13.2 x 8.8 mm ) sized CMOS sensor and features Expeed 4 processor. On the other hand, Samsung NX mini has a
20.5MP 1' (13.2 x 8.8 mm ) sized BSI-CMOS sensor .
Below you can see the 1 J4 and NX mini sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon 1 J4 and Samsung NX mini Cameras
Nikon 1 J4 and Samsung NX mini have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Nikon 1 J4 has 9% larger pixel area compared to Samsung NX mini, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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 1 J4
or the
Samsung NX mini ,
including hyperfocal distance.
