Canon Elph 115 IS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features DIGIC 5 processor. On the other hand, Kodak M530 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the Elph 115 IS and M530 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon Elph 115 IS and Kodak M530 Cameras
Canon Elph 115 IS and Kodak M530 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 Kodak M530 has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Canon Elph 115 IS, 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
Canon Elph 115 IS
or the
Kodak M530 ,
including hyperfocal distance.
