The full set of lens profiles is unavailable for jpg files even when choosing manually.

Lens profiles for jpg files very limited. Even though Lightroom will not automatically choose a lens profile for jpg files, it seems that users should still be able to assign manually. The list of lenses is woefully short.

Personally, I am not using this function in LR, I am rather using DxO Lab for developing RAW files.

This said, as far as I know, lens corrections are not possible with JPEG format. This kind of correction like the WB correction and Camera correction are only possible with RAW format

This reply was created from a merged topic originally titled Please make a way possible to use RAW Lens Profiles for JPGs.

I Use a manual Irix 11mm F4 Lens.
When i make Timelapses with Sony A7rii i want to choose JPGs instead of RAW to avoid Terabytes of RAWs.
As is use a manual Adapter the Camera did not know what Lens is attached.
When i shoot Raws its possible to correct Lens Distortions with Lightroom manually. (works fine) 
But when i import JPGs these Profiles are not choosable.
The Camera didn`t know the lens. No Distortion Correction is applied from the Camera to the JPGs. 
So there is no understandable Reason to stop me from using this profile. Why are they disabled?

Without the ability to correct the Distortions the Panoramic Stitching didn`t work. This stops my entierly Workflow and forces me to handle much more Data than needed.

Lens profiles in Lightroom and Camera Raw generally only support raw files since JPEGs may already have lens corrections applied by the camera, and there is no reliable, standard way for LR to tell. Many people have wished for the capability of manually choosing a raw lens profile for JPEGs, but that's never been implemented. However, it's straightforward to edit a profile to let it work with JPEGs; see this recipe from an Adobe engineer:

This issue got raised often. One of the reasons that lens profiles created for RAW could be wrong for JPEG is that we don't know the processing history of JPEGs. The JPEGs could be cropped, scaled, transformed in tools like PS. JPEGs could even be cropped on camera via the custom aspect ratio setup. In other words, assumptions on the geometry/optics of JPEGs could be very wrong when a lens profiles built for RAW is applied.

It makes sense that LR wouldn't automatically select the lens profile for JPEGs. But many are asking for the ability to manually select the lens profile.   I don't see the harm in that -- it would be apparent to the user if the profile isn't producing the intended effect. LR could provide a warning, "Applying a raw lens profile to a JPEG may not give a good result."
