Below you can see the Finepix Z90 and XP70 sensor size comparison.
Sensor Size and Resolution Comparison image of FujiFilm Finepix Z90 and Fujifilm XP70 Cameras
FujiFilm Finepix Z90 and Fujifilm XP70 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 Finepix Z90 has 14% larger pixel area compared to Fujifilm XP70, 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 Finepix Z90
or the
Fujifilm XP70 ,
including hyperfocal distance.
