Nikon S620 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Panasonic FH2 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine IV processor.
Below you can see the S620 and FH2 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon S620 and Panasonic FH2 Cameras
Nikon S620 and Panasonic FH2 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 S620 has 16% larger pixel area compared to Panasonic FH2, it has potential to collect more light on pixel level hence 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 S620
or the
Panasonic FH2 ,
including hyperfocal distance.
