[QUOTE="dslater, post: 363477, member: 32537"] No, not really. The parameter D is the focus spread of everything you want to bring into focus - i.e. how much depth of field you need. Once you have determined the DOF you need, this calculation tells you the f-stop to use that will give you the best possible result. This is different from the hyperfocal marks on your lens in that those marks represent the f-stop that gives you the minimal acceptable result, not the sharpest possible result. [/QUOTE]
