Sensor Size and Resolution Comparison image of Samsung TL220 and Casio EX-FH25 Cameras
Samsung TL220 and Casio EX-FH25 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 TL220
or the
Casio EX-FH25 ,
including hyperfocal distance.
