Samsung WB250F has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Samsung HZ10W has a
10.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the WB250F and HZ10W sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung WB250F and Samsung HZ10W Cameras
Samsung WB250F and Samsung HZ10W 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 WB250F
or the
Samsung HZ10W ,
including hyperfocal distance.
