Nikon S7000 has a
16.0MP 1/2.3 (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, FujiFilm AV200 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the S7000 and AV200 sensor size comparison.
Nikon S7000 and FujiFilm AV200 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 AV200 has 15% larger pixel area (2.04µm2 vs 1.76µm2) compared to Nikon S7000, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
