Both Panasonic FZ2500 and Panasonic FZ1000 have 1″ sized 20.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the FZ2500 and FZ1000 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FZ2500 and Panasonic FZ1000 Cameras
Panasonic FZ2500 and Panasonic FZ1000 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.
DxOMark Sensor Scores
Both Panasonic FZ2500 and Panasonic FZ1000 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, FZ2500 has scored 70, 6 points higher than FZ1000.

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
Panasonic FZ2500
or the
Panasonic FZ1000 ,
including hyperfocal distance.
