Fujifilm S8300 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Olympus SP-800 UZ has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III processor.
Below you can see the S8300 and SP-800 UZ sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm S8300 and Olympus SP-800 UZ Cameras
Fujifilm S8300 and Olympus SP-800 UZ 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.
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
Fujifilm S8300
or the
Olympus SP-800 UZ ,
including hyperfocal distance.
