Nikon P900 has a
16.0MP (6.17 x 4.55 mm ) sized CMOS sensor and features Expeed C2 processor. On the other hand, FujiFilm S1800 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the P900 and S1800 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon P900 and FujiFilm S1800 Cameras
Nikon P900 and FujiFilm S1800 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 FujiFilm S1800 has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Nikon P900, it has larger pixel area to collect light hence potential to 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 P900
or the
FujiFilm S1800 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
( versus 1/2.3-inch),
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.
