Olympus SP-810 UZ has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III+ processor. On the other hand, Samsung WB850F has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Below you can see the SP-810 UZ and WB850F sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus SP-810 UZ and Samsung WB850F Cameras
Olympus SP-810 UZ and Samsung WB850F 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 Olympus SP-810 UZ has 15% larger pixel area compared to Samsung WB850F, 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
Olympus SP-810 UZ
or the
Samsung WB850F ,
including hyperfocal distance.
