Samsung WB850F has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Fujifilm JX370 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the WB850F and JX370 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung WB850F and Fujifilm JX370 Cameras
Samsung WB850F and Fujifilm JX370 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 Fujifilm JX370 has 15% larger pixel area (2.04µm 2 vs 1.76µm 2 ) compared to Samsung WB850F, it has larger pixel area to collect light hence potential to 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 WB850F
or the
Fujifilm JX370 ,
including hyperfocal distance.
