Samsung SL620 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Fujifilm SL1000 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Below you can see the SL620 and SL1000 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung SL620 and Fujifilm SL1000 Cameras
Samsung SL620 and Fujifilm SL1000 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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 SL620
or the
Fujifilm SL1000 ,
including hyperfocal distance.
