Olympus 7030 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features TruePic III processor. On the other hand, Sony HX30V has a
18.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features BIONZ processor.
Below you can see the 7030 and HX30V sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus 7030 and Sony HX30V Cameras
Olympus 7030 and Sony HX30V have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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 7030
or the
Sony HX30V ,
including hyperfocal distance.
