Sony W530 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features BIONZ processor. On the other hand, Sony W730 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the W530 and W730 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony W530 and Sony W730 Cameras
Sony W530 and Sony W730 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 W530 has 14% larger pixel area compared to Sony W730, 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
Sony W530
or the
Sony W730 ,
including hyperfocal distance.
