Canon A2500 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Canon A2200 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features DIGIC 4 with iSAPS technology processor.
Below you can see the A2500 and A2200 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon A2500 and Canon A2200 Cameras
Canon A2500 and Canon A2200 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 A2200 has 14% larger pixel area (2.01µm 2 vs 1.76µm 2 ) compared to Canon A2500, 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 A2500
or the
Canon A2200 ,
including hyperfocal distance.
