14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III+ processor. On the other hand, Nikon L820 has a
16.0MP 1/2.3-inch (6.16 x 4.62 mm ) sized BSI-CMOS sensor .
Below you can see the TG-320 and L820 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus TG-320 and Nikon L820 Cameras
Olympus TG-320 and Nikon L820 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 TG-320
or the
Nikon L820 ,
including hyperfocal distance.
