Sony TF1 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Canon SX20 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 TF1 and SX20 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Sony TF1 and Canon SX20 IS Cameras
Sony TF1 and Canon SX20 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 SX20 IS has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Sony TF1, 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
Sony TF1
or the
Canon SX20 IS ,
including hyperfocal distance.
