Both Fujifilm X-A10 and Fujifilm S8200 have 16.0 MP resolution sensors but Fujifilm X-A10's sensor is APS-C (23.6 x 15.6 mm ) and Fujifilm S8200's sensor is 1/2.3-inch (6.17 x 4.55 mm ).
Since Fujifilm X-A10'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 S8200.
Another difference between these two cameras is that Fujifilm X-A10's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the X-A10 and S8200 sensor size comparison.

As seen above, Fujifilm X-A10 has a 13.1x Larger sensor area than Fujifilm S8200. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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 X-A10
or the
Fujifilm S8200 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C 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.
