"Non D-Lens Workaround for DxO Optics Pro"
Tue 16-Apr-13 11:56 AM by mpage

DxO Optics Pro uses the distance information provided by Nikon D lenses for distortion correction calculations, creating an issue for Non Nikon D-Lenses. Non D lenses do not provide this distance information.

There is a workaround for Non D-Lens when using DxO Optics Pro. I have the old version of the Nikon 300mm f/4 ED lens. Unlike the newer version of this lens, the older version is not a D lens.

The following is from a DxO Tech Support PDF file.

Download and unzip the following:

This yields “exiftool.exe”.

Copy this to a folder in a convenient location on your computer and right clicking on “exiftool.exe” select “Create shortcut”. Put the shortcut on your computer’s desktop, in your Browse Folder, or another location that is convenient to for you.

Right-click on the shortcut and select “Properties”. In the pop-up that appears click on “Shortcut” tab, go to the “Target” field and add to the line containing “exiftool.exe”: (space)-FocusDistance="99.0m" (see screenshot below) and then click "Apply" and then "OK".

Note: There is a space between the exiftool.exe and the -FocusDistance . . .

Now all you need to do is drag your non-D NEFs (or JPGs) or a folder containing these files to the shortcut and it will correct these files for you. It will save the original of any file(s) corrected with “_original” appended to it. Both the corrected and original files are saved to folder that contained the previously uncorrected file(s).

Nikon “non-D” lenses have identical optics to their “D” lens counterparts. So it is perfectly valid and correct to use a DxO Optics Pro Module for these lenses. However there is a different “chip” in a “non-D” lens than in its “D” counterpart.

Rather than transmitting back to the camera body an actual camera-to-subject distance to be incorporated in the Makers Notes EXIF data, “non-D” lenses provide an invariant distance of 0.06 meters. This causes the optical correction algorithms to initialize incorrectly. An error message “Distortion Preparation Error” is given and the processing of the NEF Raw or JPEG image file made by a Nikon camera body using one of these lenses is not possible. This workaround corrects this issue.
