Sensor Size and Resolution Comparison image of FujiFilm XP10 and Nikon S3300 Cameras
FujiFilm XP10 and Nikon S3300 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 XP10 has 32% larger pixel area compared to Nikon S3300, 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 XP10
or the
Nikon S3300 ,
including hyperfocal distance.
