Strange Issue with Nikon Z6 Raw files and Lens Correction

"Not letting me attach the nef file, even tried zipping it."

The new forum software isn't the best, to say the least. Please upload it to Dropbox or similar and post the sharing link here. (Some people use WeTransfer, but those links are only valid for a limited time.)

Not letting me attach the nef file, even tried zipping it.

Again, the issue is that pfinfante1956 is getting intermittent behavior: "The lens option comes up with 'Built In' and sometimes 'None'.  This happens randomly for images captured in the same session using the same lens." [Emphasis added]

With a sample image that shows None, we can see if it shows None in other LR configurations, indicating whether the issue is a problem with one configuration or with the image itself.

The issue on the table is: "The lens option comes up with 'Built In' and sometimes 'None'."

Nikon Z6, a mirrolesss camera with in lens in camera corrections. As such Lightroom reports as such and does not have any corrections to provide. Even if you turn that off in camera. Hence "Built-in Lens Profile applied" pops up.

This is mirrorless 101. No auto lens corrections

You might want to place a request for change over at the feedback site. Ahh, in fact you might want to add yourshef to:

I suggest you attach a sample raw that shows None to this message, which will let us quickly determine if this is an issue specific to your configuration or to the photos themselves. 

To attach a photo here: After posting the reply, click More > Edit Reply at the bottom of the reply. Then click the little paperclip icon in the lower-left corner of the reply box. Then click Apply Edits. (If you insert a photo rather than attach it, the stupid forum software will reduce its resolution and hide important details.)

Understood. But did you triple-check by typing "i" in Develop?  It is indeed not uncommon to think you're working with a raw when you're not.  (Lot's of threads here about that over the years.)

Triple-check that you're actually editing a raw file. (An easy way to do that is type "i" to cycle through the information overlays until you see the filename.)  It's not an uncommon mistake to edit a non-raw thinking it's raw -- LR doesn't make it apparent.
