Nikon S8200 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Expeed C2 processor. On the other hand, Nikon S9100 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Expeed C2 processor.
Below you can see the S8200 and S9100 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon S8200 and Nikon S9100 Cameras
Nikon S8200 and Nikon S9100 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 Nikon S9100 has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Nikon S8200, 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
Nikon S8200
or the
Nikon S9100 ,
including hyperfocal distance.
