Nikon S570 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Expeed processor. On the other hand, Sony WX80 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features BIONZ processor.
Below you can see the S570 and WX80 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon S570 and Sony WX80 Cameras
Nikon S570 and Sony WX80 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 S570 has 32% larger pixel area compared to Sony WX80, 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 S570
or the
Sony WX80 ,
including hyperfocal distance.
