Samsung WB350F has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Sony WX5 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Bionz processor.
Below you can see the WB350F and WX5 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung WB350F and Sony WX5 Cameras
Samsung WB350F and Sony WX5 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 Sony WX5 has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Samsung WB350F, 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 WB350F
or the
Sony WX5 ,
including hyperfocal distance.
