Both Fujifilm F660EXR and Fujifilm S8400W have 16.0 MP resolution sensors but Fujifilm F660EXR's sensor is 1/2-inch (6.4 x 4.8 mm ) and Fujifilm S8400W's sensor is 1/2.3-inch (6.17 x 4.55 mm ).
Since Fujifilm F660EXR's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Fujifilm S8400W.
Below you can see the F660EXR and S8400W sensor size comparison.

Fujifilm F660EXR and Fujifilm S8400W have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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 F660EXR
or the
Fujifilm S8400W ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2-inch versus 1/2.3-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
