Fujifilm XP150 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Canon A1100 IS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Digic 4 processor.
Below you can see the XP150 and A1100 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm XP150 and Canon A1100 IS Cameras
Fujifilm XP150 and Canon A1100 IS 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 A1100 IS has 18% larger pixel area (2.34µm 2 vs 1.98µm 2 ) compared to Fujifilm XP150, 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
Fujifilm XP150
or the
Canon A1100 IS ,
including hyperfocal distance.
