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, Sony W350 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Bionz processor.
Below you can see the Elph 115 IS and W350 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon Elph 115 IS and Sony W350 Cameras
Canon Elph 115 IS and Sony W350 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 Sony W350 has 14% larger pixel area (2.01µm 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
Sony W350 ,
including hyperfocal distance.
