Sensor Size and Resolution Comparison image of Panasonic FX78 and Pentax WG-1 Cameras
Panasonic FX78 and Pentax WG-1 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
Panasonic FX78
or the
Pentax WG-1 ,
including hyperfocal distance.
