Look at the images EXIF data with exiftoolGUI and see if the lens is listed. LR can only show what the camera places in the EXIF. I suspect the camera is not including that information.
The way I did this (with a much smaller set of files) was to create a Develop preset that contained only the lens profile correction then apply this preset to the desired files from the Library module, Quick Develop panel.
To work with all new imported files, I created preset that contained my desired camera profile (camera neutral) and the lens profile correction, then choose this preset during each import (import remembers the last used preset).
As Bond points out, this only works with supported lenses.
The info is definitely in exif, if I go to library module I can read it, however Lightroom for some reason has not added it to lens corrections.
ManiacJoe I was going to add lens corrections to a simple settings sync in develop mode, but, if I choose to sync lens profile corrections, will it sync that specific lens or just the auto setting?
Depends on the setting you have used.
If you select "auto", then LR will read the EXIF data and pick what it thinks best matches the lens (LR is not 100% accurate in the guessing).
I have never selected "custom", but I would assume that by manually picking the lens, you would apply that one lens to everything.
Not all lenses are available for corrections.
Well I'm adding every photo to the quick collection, selecting the lot, then going to edit mode and choosing 'auto' and it is doing absolutely nothing.
So I tried choosing Canon as the make as most of my shots would be with a Canon, and it filled in the rest of the lens info. I closed and reopened and that seems to have done the trick Thanks for your time everyone.
