Canon SX160 IS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Digic 4 processor. On the other hand, Canon SX200 IS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the SX160 IS and SX200 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Canon SX160 IS and Canon SX200 IS Cameras
Canon SX160 IS and Canon SX200 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 SX200 IS has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Canon SX160 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 SX160 IS
or the
Canon SX200 IS ,
including hyperfocal distance.
