Panasonic F5 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Samsung SL820 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the F5 and SL820 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic F5 and Samsung SL820 Cameras
Panasonic F5 and Samsung SL820 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 Samsung SL820 has 16% larger pixel area (2.31µm 2 vs 1.98µm 2 ) compared to Panasonic F5, 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
Panasonic F5
or the
Samsung SL820 ,
including hyperfocal distance.
