Sensor Size and Resolution Comparison image of Panasonic ZS70 and Canon SX170 IS Cameras
Panasonic ZS70 and Canon SX170 IS 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 ZS70
or the
Canon SX170 IS ,
including hyperfocal distance.
