One nice thing with digital images is that they have tags on it, so when you are at home you can use this tags to get all the shooting parameters (Aperture, speed, which lens was used, focal length,…) and also when you add a description to your image in your image editor it's also saved as a tag into the image file.
With old manual only lenses and in this case the 3D Lens in a Cap from Loreo you have a lot missing and empty tag fields because the camera does not know what to fill in.
To fill in the missing tags when using the LOREO 3D Lens in a Cap 9005 you can use the programm ExifTool.
exiftool -P -overwrite_original -XMP-aux:Lens="LOREO 40mm F11-22 3D Lens in a Cap 9005 MF, 3D, parallel view, APS-C" -nikon:lens="40mm f/11-22" -exif:focallength="40 mm" -exif:focallengthin35mmformat="60 mm" -nikon:minfocallength="40 mm" -nikon:maxfocallength="40 mm" -nikon:MaxApertureAtMinFocal="11" -nikon:MaxApertureAtMaxFocal="11" <file>
If you have an other camera brand you have to adjust the command line a bit or use the exif tags only.
