Sensor Size and Resolution Comparison image of Panasonic FX78 and Panasonic XS1 Cameras
Panasonic FX78 and Panasonic XS1 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 Panasonic FX78 has 32% larger pixel area compared to Panasonic XS1, 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
Panasonic FX78
or the
Panasonic XS1 ,
including hyperfocal distance.
