Hi lloyd_pdx,
Nikon N-log is natively supported in Pr v25.2, but it will require you to manually assign the color space. To do this, you may select the required clips in the timeline > right-click > Modify > Color > set Override Media Color Space to Nikon N-log/Rec2020. However, please note that this color space is designed for N-log media & not the Z-log. So it might require fine-tuning the color afterwards. You may try using the N-log profile & see if it gets you to a good starting point. You may refer to this link to learn more about Auto Detection of Log Camera Formats and Raw Media in Premiere Pro. Hope it helps.
Thanks,
Sumeet
