Nikon .NEF file and LR

[davidhammond]

Never had this problem until now.  Imported photos into LR from the desktop, and LR for some reason won't read or develop my new RAW nikon .NEF files that I took this afternoon.  So, I tried JPEG, and LR will read and develop those files without problem.  It's just the new NEF files, I get an exclamation mark next to the thumbnail print, and I get the error message "an unexpected end-of-file occurred"  or "Lightroom has encountered problems reading this photo."  Again, it's only with the Nikon NEF files, but the JPEG files there are no issues.  I even deleted LR and reinstalled it, tried different memory cards.  Anyone have any ideas or explanations?

I use a Nikon D750 and iMac. 

Thanks,

David.

What version of Lightroom ?   You need v5.7 or higher.

won't read

Do you mean you cannot import?  Does your destination folder have full Read/Write permissions?

Are you using Nikon Transfer software to import photos from the camera?  There are known bugs with some versions of this software.

A forum thread on this topic-

I have the latest version of LR.  I do the monthly subscription so it updates automatically.

Did you use Nikon Transfer to import the files from the card to the desktop?

[davidhammond]

yes

I can import, but after I do, LR won't read the NEF file. I'm starting to think maybe it's the camera.  Look at the picture I just took right now and this is what I get when I took both NEF and JPEG;

RAW .NEF file

JPEG file.

So, it turns out it must of been the Nikon View 2 transfer.  So I transferred the NEF directly from the camera into LR and there were no bugs and LR opened the RAW file without problem.
