Olympus SP-810 UZ has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III+ processor. On the other hand, Canon N has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Digic 5 processor.
Below you can see the SP-810 UZ and N sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus SP-810 UZ and Canon N Cameras
Olympus SP-810 UZ and Canon N 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 Canon N has 52% larger pixel area (3.12µm 2 vs 2.04µm 2 ) compared to Olympus SP-810 UZ, 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
Olympus SP-810 UZ
or the
Canon N ,
including hyperfocal distance.
