Sony W730 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Sony W610 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 W730 and W610 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony W730 and Sony W610 Cameras
Sony W730 and Sony W610 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 W610 has 14% larger pixel area (2.01µm 2 vs 1.76µm 2 ) compared to Sony W730, 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 W730
or the
Sony W610 ,
including hyperfocal distance.
