P: Anamorphic Lens Support (De-squeeze)

Agreed.  While I do plan on fully profiling the Catos and Remus I have, most times I just want to desqueeze, so that's how I have it setup.

I agree with this sentiment. I a simple de-squeeze function would be stellar. If it will speed up the process, I'd say forget about 'lens correction' aspect of it. Just a simple de-squeeze that can handle different ratios is what's needed. Hope this becomes a reality soon!

Yeah, the way it has to be done right now, doesn't allow the full resolution to be used.

Adding a vote here. Autofocus anamorphic lenses are now a thing, so this topic will rapidly become less niche. I'd echo other comments that this is not necessarily linked to profiling specific lenses. I personally do not want to remove all the distortion and vignetting from my anamorphics, I just need the proper pixel aspect ratio. As has been pointed out, this won't be in metadata, so it needs to be manually set.

Crucially, this should not be handled by the existing Transform controls. Even if the Aspect slider could go farther, it would be a bad way to correct for anamorphic distortion, as it would make any other transforms wonky due to the order of operations.

Pixel Aspect Ratio is well understood by other Adobe apps. Time for Lightroom to join the party. Anamorphics are a blast!

Lens profile version wouldn't work for vintage lenses, anamorphic adapters, or custom made/modified lenses.

This would also likely be significantly more dev time than just a ratio input to de-squeeze.

It is nice having it for sure.

yeah but specific desqueeze funtion would be good too. for vintage stuff that there might be no lens profile. both would be key though

Just basic lens profiles are all that is needed.

I'll add to the sentiment of adding anamorphic de-squeeze support in light room. Would be super helpful please and thank you!
