Below you can see the SX280 HS and ZS35 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon SX280 HS and Panasonic ZS35 Cameras
Canon SX280 HS and Panasonic ZS35 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
Panasonic ZS35 ,
including hyperfocal distance.
