Samsung DV300F has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Canon SD1300 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 DV300F and SD1300 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung DV300F and Canon SD1300 IS Cameras
Samsung DV300F and Canon SD1300 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 SD1300 IS has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Samsung DV300F, 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
Samsung DV300F
or the
Canon SD1300 IS ,
including hyperfocal distance.
