D750 not recording lens model in EXIF data

My Nikon D750 stopped recording the lens data (which lens is mounted) about a month and a half ago. Other EXIF Data is being recorded such as the photo settings. I use all Nikon Branded Lenses. The lens data is not being written to the file by the D750 for any of the lenses. Has anyone else experienced this?

Re: D750 not recording lens model in EXIF data

Hmm... I don't think Nikon cameras actually record the lens make and model at all. They only populate one field which is a generic field that contains the max and min aperture, and max and min focal length. So for a 70-300 4-5.6 lens the field looks like this: 70, 300, 4, 5.6. Take a look at the raw EXIF with Lightroom or similar and you'll see this value.

An alternative theory would be that the lens model data is in a proprietary EXIF field that only Nikon software will read (for lens corrections and such).

Re: D750 not recording lens model in EXIF data

I don't think this is the case. Lightroom metadata is unknown lens. Prior to a month and a half ago Lightroom knew which make and model lens was attached. Now it shows nothing or unavailable. So I checked the original files to see if the exif data for the lens was in the properies.

Right, so check the raw EXIF like I said. Most likely the field I mentioned is not populating. Try resetting the camera to factory defaults.

The exif data for the lenses doesn't show on Windows 10 for me.

I can see the lens data when using the Exiftool software however!

This was a bug in Lightroom C 2015.5 and Lightroom 6.5 which only appears for Nikon DSLRs. The latest Lightroom release corrects the problem.

Re: D750 not recording lens model in EXIF data

I updated lightroom. it still doesn't know what lens I used. Will not figure that out since it wasn't working on import? I haven't importing new photos yet.

Re: D750 not recording lens model in EXIF data

ok, Never mind. It looks like it figures it out if i tell it to read the metadata from the file.

Thanks for the help.

Re: D750 not recording lens model in EXIF data

There are instructions which accompany the update.

(1)  Select all the NEF files in Lightroom which do not show the correct lens information.

(2)  Now "Write Metadata to Files"

(3)  With the images still selected you then "Read Metadata From Files"

Done.

Re: D750 not recording lens model in EXIF data

If you Read Metadata From Files without first executing Write Metadata to FIles then you have clobbered all edits you have done to the affected images.

In your Library module, use the Metadata filter to find all images with "Unknown Lens" since March of this year. The collection should include all the images you've imported since the version 6.5 update, which has the bug.

  • Ctl/Cmd, A to select all "Unknown Lens" files
  • Ctl/Cmd, S to save Metadata to the files. If you shoot in Raw, this will create sidecar XMP files preserving all the work you've done to the images since import. This is an important step because, if skipped, the next step will undo any editing you've done to the files.
  • Ctl/Cmd, R to read Metadata from the XMP files. This will read and display the Metadata, including the lens ID info.

Good luck.

Not so , if you look at my Flickr exif the D500 and the D810 record different lens info but they both record the Lens ID # , the D810 records Model also, both record focusing distance.
