Below you can see the WB750 and WB700 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung WB750 and Samsung WB700 Cameras
Samsung WB750 and Samsung WB700 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 WB750
or the
Samsung WB700 ,
including hyperfocal distance.
