Nikon P310 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Olympus SZ-10 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III+ processor.
Below you can see the P310 and SZ-10 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon P310 and Olympus SZ-10 Cameras
Nikon P310 and Olympus SZ-10 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 SZ-10 has 15% larger pixel area (2.04µm 2 vs 1.76µm 2 ) compared to Nikon P310, 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
Nikon P310
or the
Olympus SZ-10 ,
including hyperfocal distance.
