Sensor size is what determines the circle of confusion, and therefore how much
depth of field Ricoh CX6 gives you at any given aperture.
You can
calculate
the exact depth of field for the Ricoh CX6
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.
