P: Disable built-in lens profile

I tried to figure EXIFtool out and it doesn't make much sense. It would be nice if there was an easy way to use EXIFtool in Lightroom.

just use exiftool and get null the tags in DNG files ...

Automatically and irreversibly applying built-in lens profiles is also a serious bug in Adobe Camera Raw. When processing DNG files from, for example, a drone like the DJI Mavic 2 Pro, Adobe Camera Raw automatically applies the lens correction built into DJI’s DNG files. As a result, lens distortion is applied and CANNOT BE UNDONE. The lens distortion correction is so extreme that it causes serious image degradation, especially in the corners. Adobe: What is the point of a raw file if you force the user into accepting edits that cannot be undone?! Adobe has just turned all the advantages of a raw file into all the limitations of a JPEG.

To get around this problem, I’ve had to switch to a raw editor that does not do this. As a result I purchased Affinity Photo. The more I use Affinity Photo, the more I like it. And I especially like it in consideration of Adobe’s recent threat to price their Photo plan at $20 per month instead of the current $10 per month. To be honest, I’m now one step away from leaving Adobe once and for all, and this is coming from a professional photographer!

I've just bought a Fuji XT30. There is an in-body option to enable or disable lens distortion correction, which means that Fuji - just as Nikon - is perfectly fine with using the sensor uncroped. Unfortunately, LR doesn't honor the user choice and forces the profile to be enabled.

This feature request beeing 1 year old, and still not taken into account by Adobe, I now beleive that they will never put the 1/2 day developer effort to solve the issue. I've now switched to Capture One Pro which lets the user the creative choice of which correction to apply. For multi-device work, backup and face recognition, I subscribed to Mylio which compliments COP just perfectly. So bye bye, Adobe.

It is really a shame that an official rep of Adobe doesn't even write a word or too, even "we won't support that because we want to force you to crop your sensor". At least, we would know. It was a memeber of the support team who asked me to post here to get feedback, and I have none.

This is what I believe should be addressed and is probably a bug in ACR.  I turned off "Auto distortion control" in my Z7.  When I load a NEF in NX-D distortion correction is not automatically applied but it is in ACR.  The information to apply correction or not is properly written to the file.  Adobe is either not reading it correctly or ignoring it.

Interestingly, if I turn off vignetting control in camera it's not automatically applied in ACR (nor in NX-D) as expected.  There is at least some logic in ACR to turn on/off corrections based on what's written to the file...

At the end of the day, these are RAW files and users should be given the option to turn on/off any correction like this during processing.  If I wanted settings baked in straight out of the camera I'd shoot JPEG.  There's no reason this can't be done in ACR if it can be done in other RAW processors.

After getting a Nikon Z6 I am too for the first time effected by ACR applying a built-in lens profile. Since I disabled this inside the camera and Nikon itself is not applying in NX-D I really wish Adobe would stop patronizing me. It's an absolute nogo, Adobe!

John was quicker than me but he is absolutely right. The sharpening settings for Z6 and Z7 files have nothing to do with the lens profiles that are also built in to the nef files. The sharpening settings are dependent on the in-camera sharpening settings and are done by simply writing xmp camera raw default metadata into the nef file that Lightroom and camera raw pick up. I really wish there was a way to disable the built-in lens profile. 

"Those built-in profiles can change the sharpening and noise reduction settings. Here's an example from the Nikon Z7. ... t looks to me that Nikon is instructing Lightroom to modify the sharpening and noise reduction settings."

The Z6 and Z7 embed LR develop settings in the XMP metadata of their raw files.  See this thread: https://forums.adobe.com/message/10862123.  

These embedded develop settings are different, and have different capabilities, from the built-in lens profiles that the cameras also embed in the photos.  The embedded develop settings can be easily disabled using an Import develop preset.  But the embedded built-in lens profile can't be disabled (at least from within LR).

Those built-in profiles can change the sharpening and noise reduction settings. Here's an example from the Nikon Z7. This is a SOC RAW file. It looks to me that Nikon is instructing Lightroom to modify the sharpening and noise reduction settings.

It's my understanding that the Adobe LR and ACR built-in lens profiles apply, only distortion, vignetting, and chromatic aberration correction and not necessarily all of them for specific camera models. Take a look at this post, which may be what you're seeing:
