Sensor Size and Resolution Comparison image of FujiFilm S1600 and Fujifilm Real 3D W3 Cameras
FujiFilm S1600 and Fujifilm Real 3D W3 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.
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 S1600
or the
Fujifilm Real 3D W3 ,
including hyperfocal distance.
