Sony W570 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features BIONZ processor. On the other hand, Sony W560 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features BIONZ processor.
Below you can see the W570 and W560 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony W570 and Sony W560 Cameras
Sony W570 and Sony W560 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 Sony W560 has 14% larger pixel area (2.01µm 2 vs 1.76µm 2 ) compared to Sony W570, 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
Sony W570
or the
Sony W560 ,
including hyperfocal distance.
