Olympus 6010 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III processor. On the other hand, Sony W710 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the 6010 and W710 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus 6010 and Sony W710 Cameras
Olympus 6010 and Sony W710 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 Olympus 6010 has 35% larger pixel area compared to Sony W710, 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
Olympus 6010
or the
Sony W710 ,
including hyperfocal distance.
