"No focus distance in EXIF?"



Nikon DSLR bodies take subject distance from "D" lenses and store it in image metadata. The EXIF metadata reader I use can't find focus distance in V1 images like it can in D200/D300/D700 images. Is the information not there or is it present in a new form the tool can't understand?

I find focus distance useful when taking closeups of live, moving insects because I can calculate the size of the subject. I know the magnification ratio at reported focus distances for my macro lenses.

John,

Nikon stores this information is their own LensData area.
They often change the layout of the information.
I expect that when the new layout is decoded you'll see the information in newer versions of your Exif reader.

It could be longer than usual as the version information for this information jumped from 2.04 to 4.00 so that sounds like a major change rather than a minor tweak.

Exiftool is often one of the first to support new cameras in this area.
