Lens Profiles apply to Camera Raw, Lightroom Classic, and the Lightroom Ecosystem products (Desktop, Mobile, and Web).

Lens Profiles are available for a wide array of lenses. Not every lens is currently profiled, and of those profiled, not all are profiled for all camera and file types. For example, there may be a profile for a particular lens and camera mount for the raw file but not for the JPEG. Normally, profiles for JPEG are not supplied unless the camera does not apply a correction (e.g. iPhone, GoPro). 

A complete list of profiled lenses can be found here: https://helpx.adobe.com/camera-raw/kb/supported-lenses.html

Lens correction for all Micro 4/3 (MFT) lenses and many newer cameras, including Panasonic and Olympus cameras, and other cameras (including Fuji X,  Leica Q, and Nikon Z series)plus many point-and-shoot models from Canon) happens automatically without any interaction by the customer. A notation will appear in the Lens Correction Panel designating this. 

Note: You should not expect to find any profiles listed in the pop-up notes, because the corrections are always applied.

If you are unsure whether your lens is supported automatically refer to the "info" button/icon on the Lens Corrections tab.

If your lens is not on the supported lens list and is not one of those whose correction happens automatically, you can create your own profiles using the Adobe Lens Profile Creator. Download the Adobe Lens Profile Creator: https://helpx.adobe.com/photoshop/digital-negative.html#resources 

If you desire an Adobe-created Lens Profile, please make your request in the comments of this thread. Be sure to include the full lens model/description and the camera mount you desire. ETAs for new lens profiles are not available.

Keep in mind that lens profiles cannot be made for tilt/shift lenses, and the tilt or shift settings cannot be recorded in the Exif data. A feature request exists here for Tilt-Shift Lens Profiles: https://community.adobe.com/t5/camera-raw-ideas/p-lens-profiles-for-tilt-shift-lens/idi-p/12221166 

Note: The Lens Profile Creator is currently supported for Windows and 32-bit Versions of the Mac OS. 

ETAs are not available for any lens request.
