Fujifilm JX370 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . 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 JX370 and WB850F sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm JX370 and Samsung WB850F Cameras
Fujifilm JX370 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 Fujifilm JX370 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
Fujifilm JX370
or the
Samsung WB850F ,
including hyperfocal distance.
