Sensor size is what determines the circle of confusion, and therefore how much
depth of field Pentax XG-1 gives you at any given aperture.
You can
calculate
the exact depth of field for the Pentax XG-1
at any focal length, aperture and subject distance, including the hyperfocal distance
for landscapes and how close you can get before the focus zone becomes too thin.
