Sony S2100 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Bionz processor. On the other hand, Sony S2000 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Bionz processor.
Below you can see the S2100 and S2000 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony S2100 and Sony S2000 Cameras
Sony S2100 and Sony S2000 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 S2000 has 33% larger pixel area (3.13µm 2 vs 2.34µm 2 ) compared to Sony S2100, 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
Sony S2100
or the
Sony S2000 ,
including hyperfocal distance.
