Sensor Size and Resolution Comparison image of Canon ELPH 300 HS and Olympus VG-160 Cameras
Canon ELPH 300 HS and Olympus VG-160 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
Canon ELPH 300 HS
or the
Olympus VG-160 ,
including hyperfocal distance.
