Both Panasonic LF1 and Canon S100 have 1/1.7-inch sized 12.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the LF1 and S100 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic LF1 and Canon S100 Cameras
Panasonic LF1 and Canon S100 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.
DxOMark Sensor Scores
Both Panasonic LF1 and Canon S100 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, LF1 has scored 52, 2 points higher than S100.

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 LF1
or the
Canon S100 ,
including hyperfocal distance.
