Nikon 1 J5 has a
21.0MP 1' (13.2 x 8.8 mm ) sized BSI-CMOS sensor and features Expeed 5A processor. On the other hand, Panasonic ZS300 has a
20.0MP 1″ (13.2 x 8.8 mm ) sized MOS sensor and features Venus Engine processor.
Another difference between these two cameras is that Nikon 1 J5's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the J5 and ZS300 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon 1 J5 and Panasonic ZS300 Cameras
Nikon 1 J5 and Panasonic ZS300 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.
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 J5
or the
Panasonic ZS300 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1' versus 1″ ),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
