Fujifilm S8600 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, FujiFilm S2500HD has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the S8600 and S2500HD sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm S8600 and FujiFilm S2500HD Cameras
Fujifilm S8600 and FujiFilm S2500HD 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 S2500HD has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Fujifilm S8600, 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
Fujifilm S8600
or the
FujiFilm S2500HD ,
including hyperfocal distance.
