12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the HZ10W and HZ25W sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung HZ10W and Samsung HZ25W Cameras
Samsung HZ10W and Samsung HZ25W 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. On the other hand, since Samsung HZ10W has 35% larger pixel area compared to Samsung HZ25W, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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 HZ10W
or the
Samsung HZ25W ,
including hyperfocal distance.
