Samsung ST6500 has a
16.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Panasonic FX90 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the ST6500 and FX90 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung ST6500 and Panasonic FX90 Cameras
Samsung ST6500 and Panasonic FX90 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 Panasonic FX90 has 32% larger pixel area (2.31µm 2 vs 1.74µm 2 ) compared to Samsung ST6500, 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 ST6500
or the
Panasonic FX90 ,
including hyperfocal distance.
