Distance or Depth-of-Field Scale? I have a Nikon D70 with the kit that includes the Nikkor 18-70mm lens. I notice that there is a distance scale on the lens. Is there any real use for this, other than feedback about how far you have focused? There does not seem to be any documentation with the lens about depth-of-field information for various distances for the lens, and I didn't know if I was just confused, or what. Could someone help me sort out what the distance scale is for, and what I can use it for with regard to depth-of-field? Thanks in advance.

The focus distance scale can be used for prefocusing to a distance, or to give the distance to use in the guide-number formula if you are doing flash exposure manually. But, like most autofocus zoom lenses, it is not practical to include a depth-of-field scale on the Nikon 18-70. DOFMaster is a handy freeware program for creating depth-of-field scales customized for your lenses.
