Samsung Galaxy Camera 2 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features 1.6GHz Quad-Core Exynos processor. On the other hand, Olympus SP-820UZ has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the Galaxy Camera 2 and SP-820UZ sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung Galaxy Camera 2 and Olympus SP-820UZ Cameras
Samsung Galaxy Camera 2 and Olympus SP-820UZ 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-820UZ has 15% larger pixel area (2.04µm 2 vs 1.76µm 2 ) compared to Samsung Galaxy Camera 2, 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 Galaxy Camera 2
or the
Olympus SP-820UZ ,
including hyperfocal distance.
