P: Lens metadata field missing on import

Since updating Photoshop and Lightroom, I've noticed that the aux:lens metadata field is being deleted from my images on import, such that there is no lens listed after import. I've determined that it's Camera Raw 9.5 that seems to be the culprit, as lens metadata is retained if I use an older version of the DNG Converter v8.8 to import the same images.

For example, I had an image shot on a Sony RX100 III at 8.8mm. If I import this image with the old version of DNG Converter, and then open the converted DNG in Photoshop, the lens is reported with the full-frame equivalent focal lengths, i.e., 24-70mm F1.8-2.8, and the raw metadata has the correct aux:Lens field (24-70mm F1.8-2.8).

Conversely, if I import the same image directly into Photoshop or Lightroom, the metadata will display the correct focal length, but will not display the lens information; Lightroom reports this only as "unknown lens," and in Photoshop the aux:Lens field is missing completely.

For now, I will use the old version of DNG Converter as a workaround, but this is inconvenient, and really should be fixed.

    John has kindly posted the link to my thread and a sample image and would also like to add that the problem appears on both my iMac and my MacbookPro.  So, it is not a case of a bad update on a single machine.

    Also, to re-iterate from the more detail info in the link to my post that John has kindly posted, the lens correction function within Lightroom does correctly detect the lens model used for each image.  The display of the EXIF info is lacking and thusly, in the library database it is listed as an unknown lens.

    So it "seems" that Lightroom does see the EXIF fields in the photo for the lens model, but does not display a lens model in the info display and apparently does load the info into the "database".

    Good point. I should clarify my original post to note that I haven't actually checked this with my non-Nikon cameras; the Sony RX100 example was to point out the aux:Lens field that's missing in my imported Nikon NEF files. I can re-test with Sony and Panasonic RAW files at a later point in time, but I suspect that these will import correctly.

    I looked at a number of raw files from Canon, Sony, Pentax, Fujifilm, and Nikon cameras. Of the files I looked at, only Nikon raw files (from several different models) show the problem -- lens info imported into LR 5 but not LR 6.

    Here's another example of the problem from this thread, another NEF: https://drive.google.com/file/d/0B61zs8oGmc6ENzFOUWl1VU12aWs/view?usp=sharing

    I have reproduced it to. In my 2015.5 on OS-X the lens metadata is missing. On my 2015.4 (Win 10) the information is showed. Looks indeed like a bug in 2015.5

    Yes, that's exactly the issue I'm having. The lens profile does appear to be imported correctly, but the Lens metadata is missing in 2015.5. I've only tested on OS X, but can re-test on Windows 10 tonight.

    I think there's a bug in LR CC 2015.5 / 6.5 with respect to lens information.  I downloaded Roelof's sample NEF: https://www.dropbox.com/s/nid1pimmdpsiup4/RM_20160227_134751.nef?dl=0

    When I import it into 2015.5, the Library Metadata panel doesn't show any Lens and the Lens column in the filter bar shows Unknown Lens:



    But the Enable Profile Corrections panel in Develop infers the correct lens and profile:



    In LR 5.7.1, however, the Metadata panel and the Lens column in the filter bar show the correct lens:



    Tested on both OS X 10.11.2 and Windows 10.

    Hmm, Bridge is showing me the lens information in both situations. Only thing i did was downloading te files and open them in bridge:
    NEF: https://www.dropbox.com/s/6hp7u3ffvmyrp9i/NEFinBridge.JPG?dl=0
    DNG: https://www.dropbox.com/s/rcgzacyy5zs8vze/DNGinBridge.JPG?dl=0

    Lightroom does show the same information.
    I'm testing on a windows 10 environment. I will repeat it on my Macbook. When the results are differtent i let you know.

    This is the RAW file directly copied from my camera: https://drive.google.com/file/d/0B4M7Ie_2T_HgV2lhTFR2dDdhT0U/view?usp=sharing

    This is a DNG file after I imported the image using Lightroom, and then told it to export a DNG: https://drive.google.com/file/d/0B4M7Ie_2T_Hgb0xPc01uT0Q0Y2s/view?usp=sharing

    I suspect the first image will have the lens info, whereas the second will not.

    You could send me one of your images as a sample. I can make a screenshot of what Lightroom shows. Here is a screenshot of the information Bridge is showing me of the DNG a made with the latest DNG converter: https://www.dropbox.com/s/sfcel4o5zqllurh/lensinfo2.JPG?dl=0
