Panasonic FP3 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine IV processor. 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 FP3 and S70 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FP3 and Nikon S70 Cameras
Panasonic FP3 and Nikon S70 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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
Panasonic FP3
or the
Nikon S70 ,
including hyperfocal distance.
