Sensor Size and Resolution Comparison image of Casio EX-Z2000 and Nikon S4300 Cameras
Casio EX-Z2000 and Nikon S4300 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 Casio EX-Z2000 has 14% larger pixel area compared to Nikon S4300, 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
Casio EX-Z2000
or the
Nikon S4300 ,
including hyperfocal distance.
