Below you can see the WB700 and SZ-31MR iHS sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung WB700 and Olympus SZ-31MR iHS Cameras
Samsung WB700 and Olympus SZ-31MR iHS 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
Samsung WB700
or the
Olympus SZ-31MR iHS ,
including hyperfocal distance.
