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.

    What does DNG validation bring me?  If the data is corrupt I'm screwed anyway.  Unless you run these validation procedures in the background that buys you really nothing.  Other than maybe a false sense of security.

    I'd rather stick with a RAW format where the camera manufacturer could help recover, or in the case of the more popular formats (Canon, Nikon, etc) the programming community at large could help recover bad data.

    I'm not about to save my precious photo files into a proprietary file format such as Adobe's DNG. Who know what the future brings with DNG?? 

    In the past, I've loved the WMF format (a vector format for graphics) and have many many files in that format. It was a VERY popular graphic file format. But it is now an unusable format! In my MAC. I have had to purchase a converter so I can still use my WMF files - in a different format. 

    I was a Windows user and also loved CorelDraw and Paint Shop Pro. As a MAC user, I can not open .CDR files nor .PSP files!! Though I just Googled and maybe... ugh!!

    So, to repeat myself... who knows the future of the Adobe "proprietary" DNG file format? No one. I will not be using DNG for these reasons.

    In combination with Lightroom DNG offers someting no other format does: checking on file integrity with 'DNG validation'. Or in other words: peace of mind

    They are certainly quick about getting our monthly fee.  Right on time every month!

    Why would anyone ever convert to DNG?  I can still open MRW (Minolta RAW) files from my Dimage7 in Lightroom, Canon 10D, Nikon D300, etc all are still supported.  And even if Adobe would stop supporting old cameras we could use another app like DCRAW to convert to TIFF or JPEG.

    DNG is a nice but very niche format.  And, like RAW is proprietary technology.  I'd rather keep in the various RAW formats and convert if they become unsupported rather than convert to another proprietary format.

    It's profoundly unsettling to (apparently) lose data from photographs as they're imported. Users who do not frequent these support sites are not likely to know why their data seems to be disappearing on import. Assurances on these boards that the data remains buried in the file are not entirely reassuring to users who convert to DNG because the conversion to DNG has a "black box" feel to it. So it would good if Adobe produced a fix quickly (three weeks and counting  for what is surely not a huge bug is long, especially for customers who must pay a subscription fee every month!) and made more of a proactive effort to keep its customers informed about the nature of the problem.

    Having the same problem with my Nikkor lenses - this is very unsatisfactory and increasingly inconvenient - please fix as a matter of priority. While doing so, please ensure that the EXIF lens data on photos imported into the current release is correctly displayed on the new, fixed release.

    Buongiorno, da quando ho installato l'ultima realease - 2015.5 , dopo
    che importo una serie di raw, vado sui filtri nel modulo Libreria è
    seleziono Metadati-Obiettievo, il risultato è "Obiettivo sconosciuto".
    Ho provato sul portatile che ha la stessa versione è si ripete la stessa cosa.
    Ho poi utilizzato la versione LR 6.2  e ripetendo le
    stesse operazioni tutta funziona bene con l'indicazione corretta delle
    ottiche utilizzate.

    That's only a solution if the files are RAW though. In the case of JPEGs, write metadata to files is a destructive operation that actually changes the headers on the original files 😕😕

    It wasn't Nikon specific for me.  I was importing some older Canon .cr2 files with the
    current version into new Lightroom libraries and lens model did not come with them!

    I hope the fix is coming rapidly as well.  They don't waste time collecting their subscription fees!
