Canon N has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Digic 5 processor. On the other hand, 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.
Below you can see the N and SP-810 UZ sensor size comparison.
Sensor Size and Resolution Comparison image of Canon N and Olympus SP-810 UZ Cameras
Canon N and Olympus SP-810 UZ 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 compared to Olympus SP-810 UZ, 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
Canon N
or the
Olympus SP-810 UZ ,
including hyperfocal distance.
