Permissible circle of confusion : 0.05mm
When you are focusing on a given subject, objects in the foreground and background may appear out of focus depending
on the F stop in use.
For greater depth of field, the lens needs to be stopped down to a higher F stop number. To determine the exact depth of
field range at different aperture settings, the depth of field scale on the lens should be used.
For more details, please refer to the depth of field chart.
