Canon N100 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor and features DIGIC 6 processor. On the other hand, Canon S95 has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CCD sensor and features Digic 4 processor.
Below you can see the N100 and S95 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon N100 and Canon S95 Cameras
Canon N100 and Canon S95 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 S95 has 20% larger pixel area (4.16µm 2 vs 3.46µm 2 ) compared to Canon N100, 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 N100
or the
Canon S95 ,
including hyperfocal distance.
