Add it manually. LR should find the manufacturer and lens when you use the pull-down menus and click on them.

Hi Jonathan.  Many thanks.  

I am very new to this and not sure what to do.

The lens I want to add is supported but does not appear in the list when I click on Canon...  It is the Standard 300mm 2.8 lens?

Hi Joanthan

Another thing I am having problems with is that I am missing 2 of the 4 options that used to be in Lightroom Lens Corrections panel, I am working from within the Develop Module.

Thanks

Lens profiles are specific to file format (raw, JPEG) and most lenses like the Canon 300mm F2.8 only have a raw lens profile. There is a way to "modify the raw lens profile to make it usable with JPEG files, but there are some caveats. A JPEG file will exhibit different vignetting dependent on the in-camera settings. Secondly correction can be applied in-camera for vignetting (peripheral illumination) and with some camera models distortion correction as well. Applying a lens profile inside LR will over-correct the vignetting and/or distortion. There's also no way to determine if these camera settings were already applied to the JPEG file inside LR for some camera models.

If you would still like to try converting the raw lens profile for JPEG file usage let me know what system (Mac, Windows) you are using.

All of this said may I ask why you aren't shooting raw file format or raw + JPEG?
