Yes, thank you. I just wanted to be clear that this represents a lack of support from Apple. By contacting them you will be letting them know you want support for your NEF files.
Kind regards,

Hi, @Charlie.D .
I have already asked Apple this question, but they did not reply yet. Through my own attempts, I have found a possible solution. I previously chose to use the default photo format "High Efficiency※" on Z8. Now I have changed the photo format of Z8's RAW photos to "Lossless Compression". Now iPad Photos can be opened and Lightroom for iPad can also be opened smoothly. Although the number of photos taken may decrease, at least it is usable on iPad. It seems that Apple has not adapted to the compression mode of "High Efficiency※" yet.
Thank you for your help all along!:)
