The NEF files from that camera are not compatible with LR5. You need LR 6.5 or higher. The latest version is LR6.8
Alternatively convert to Adobe raw (DNG) and the DNG files will work with LR5.
You can batch convert a whole folder of raw images into Adobe raw (DNG) and the dng files will be backward compatible with your software
If I'm converting to a different file format, doesn't that defeat the purpose of shooting in Raw?
Plus, I did try a trial version of 6.something several months ago. It could import the photos but the image quality of the preview was so poor I couldn't pick the good from the bad. Do you know if this problem has also been fixed in version 6.8?
DNG has all the same image quality as a NEF.
I’ve not seen any poor quality previews in the import dialog but I tend to import everything on the card and then decide what to keep after viewing the larger Library previews or after viewing 1:1 to check focus/sharpness.
Have the NEF files been previously used in Nikon software? That can sometimes cause problems.
If you have already used the trial and don’t want to pay for the 6.8 upgrade, I suggest you try the DNG converter on a folder of NEFs. Then import the DNG files into LR.
These are raw images right from the card. I'll try the DNG format. Thank You for your help!
