Missing lens profiles in Lightroom

If this is a Z-series Nikon, the raw file will have the profile built in and Lightroom uses it by default (in fact you extremely annoyingly can't turn this off if your camera is one of the first generation of Z's). You won't see the lens in the popup by default if it is a non-Z lens but it is still being corrected for. You should be able to select the lens if it is non-Z but you will be doing double correction in that case so you really should not do that.

If your camera is not a z-series mirrorless one, but a standard DSLR, then something else is going on.

What camera?

For some lenses, for some camera models, lens correction info gets automatically included in the Raw file and then automatically enacted onto the image by LrC 'without the option'. The Adobe lens-profile based corrections method then becomes redundant, and no Adobe lens profile for that particular lens would be offered.

However for older or more specialist lenses and especially third-party ones - or when a mount adaptor of some sort is intervened - the camera body does not have the appropriate lens recognition and availability of corrections information, to include into the Raw file it produces. So in those cases the LrC lens profile panel will not show that automatic correction has been applied. You would then be looking for a suitable Adobe- or user-generated profile to select and apply.

In some cases the design decisions governing the lens optics are such that software correction is more or less compulsory. This may even benefit the user (if the lens can thereby be lighter, cheaper, smaller, simpler). It is then in the manufacturer's interest to make sure images from this lens will never get seen "naked" of appropriate software correction. Just to spare the engineers' blushes! I expect those manufacturers will duly make sure behind the scenes, that e.g. Adobe can read, interpret and apply such so called 'built in' correction  - agreeing maybe that this must be non-defeatable - as part of adding its own Raw support for each new camera model.

The lenses supported by LrC at present are listed in this document https://helpx.adobe.com/camera-raw/kb/supported-lenses.html

Please check if your lens is listed. If it isn't then provide the exact name and specification of the lens (e.g. Nikon AF-S NIKKOR 16-35mm f/4G ED VR). We can then merge your request into the lens support request thread.
