Fujifilm S1500 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Samsung CL80 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the S1500 and CL80 sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm S1500 and Samsung CL80 Cameras
Fujifilm S1500 and Samsung CL80 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 Fujifilm S1500 has 41% larger pixel area compared to Samsung CL80, it has potential to collect more light on pixel level hence 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
Fujifilm S1500
or the
Samsung CL80 ,
including hyperfocal distance.
