Both Canon SX280 HS and FujiFilm F80EXR have 12.0 MP resolution sensors but Canon SX280 HS's sensor is 1/2.3-inch (6.17 x 4.55 mm ) and FujiFilm F80EXR's sensor is 1/2-inch (6.4 x 4.8 mm ).
Since FujiFilm F80EXR'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 Canon SX280 HS.
Below you can see the SX280 HS and F80EXR sensor size comparison.

Canon SX280 HS and FujiFilm F80EXR 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
Canon SX280 HS
or the
FujiFilm F80EXR ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus 1/2-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.
