Kodak FZ45 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Nikon S70 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Expeed processor.
Below you can see the FZ45 and S70 sensor size comparison.
Sensor Size and Resolution Comparison image of Kodak FZ45 and Nikon S70 Cameras
Kodak FZ45 and Nikon S70 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 S70 has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Kodak FZ45, 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
Kodak FZ45
or the
Nikon S70 ,
including hyperfocal distance.
