I reckon when we get down to basic physics, we can't say that absolute focus is a knife edge across an image mediated by the aperture and distance from the subject. We can only define focus in relative terms. I believe that view is what you have in mind. And I think it's correct. br - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
