Below you can see the FH27 and ZS10 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FH27 and Panasonic ZS10 Cameras
Panasonic FH27 and Panasonic ZS10 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.
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 FH27
or the
Panasonic ZS10 ,
including hyperfocal distance.
