FujiFilm S1800 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Fujifilm S1 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the S1800 and S1 sensor size comparison.
Sensor Size and Resolution Comparison image of FujiFilm S1800 and Fujifilm S1 Cameras
FujiFilm S1800 and Fujifilm S1 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 compared to Fujifilm S1, 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
FujiFilm S1800
or the
Fujifilm S1 ,
including hyperfocal distance.
