Lightroom: Create smart collections based on "Lens ID" or arbitrary Exif fields

I have taken photos with a Nikon 14mm f/2.8 lens and a Samyang 14mm f/2.8 lens and I would like to be able to create a smart collection differentiating each of them. Both lenses are only identified by "14.0 mm f/2.8" in Lightroom - which means that there is not way to tell them apart.

Looking at the XML for the Exif data from each lens, Lightroom identifies the lens using the "aux:LensInfo" tag (which is identical for both lenses).

The Exif data also contains a "aux:LensID" tag which differs between the two lenses ("107" for the Nikkor and "74" for the Samyang").

I would like to request a new feature - being able to create smart collections based the "Lens ID" Exif field. It would also be useful to be able to create smart collections based on arbitrary Exif fields (this would be a more generalised solution to my problem).

Try this plug-in and if the Lens Info meta-value field doesn't have different information then ask the plug-in writer about splitting out the aux:LensID

Thanks for the link to the plug-in. It does not specifically have an option for filtering by the "aux:LensID" Exif tag but it does have an option to isolate images according to "Lens Description" (which I suspect takes the "LensID" field into account). Filtering images according to "Lens Description" will differentiate between the two 14mm lens and allow me to create static collections.

It does however not seem possible to create dynamic collections that are automatically updated with the plug-in (as is the case with smart collections). This is why I am requesting that the Lightroom team add this filtering capability to smart collection creation.

You can work this around by using ExifTool before importing:

exiftool.exe "-Lens<LensID" DSC_1234.NEF

Or for all files in a folder:

exiftool.exe "-Lens<LensID" *

This will copy the LensID field (more descriptive field) to Lens field (typically only focal length and f-stop), which is used by Lightroom, so you can directly filter by it.
