Casio EX-S200 and Ricoh CX5 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.
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
Casio EX-S200
or the
Ricoh CX5 ,
including hyperfocal distance.
