Google: “Use a Nikon D5200 for a week. Previously I had a D5000. Both types of cameras should be supported by Lightroom 4.4. Only the program can not import my new RAW files. Why is that?”
This should probably be posted in the Lightroom forum not the Adobe Camera Raw forum, but I’ll try to answer:
Did you use an old Nikon Transfer to copy your files, or have you reviewed them with an old View NX? The older Nikon programs will corrupt the NEFs from newer Nikon cameras so you need to use the newest versions, that came with your D5200 or not use them at all.
What method are you using to transfer your NEFs to your computer?
Now it works!
Thanks a lot!!
