Why doesn’t Lightroom auto-detect my Tamron lens for profile corrections?

In Lightroom 5, lens corrections are automatically detected for my other lenses, but not for my Tamron 70-300. With Tamron images, I have to manually choose the lens make first, and then Lightroom recognises the model and focal length settings.
Why does this happen, and is there anything I can do about it?

Lenses have different identification strings depending on how well the camera can identify the lens.
For example a Canon lens on an Canon camera may be identified in the EXIF information as EF24-70mm f/2.8L USM, while a Sigma lens on the same camera may be identified as just 50-500mm.
The first one can be identified to the exact lens model, while the second one might match several lenses. When the identification string in the EXIF info doesn't contain enough information, you have to choose the make to narrow it down enough for Lightroom to be able to pick out the single model.

Generated from our catalog & community — verify before relying on it.
Lightroom relies on the lens information written into the photo’s EXIF metadata. Some camera/lens combinations record a very specific lens name, while others only record a more generic identification string.
If the EXIF data clearly identifies a single lens model, Lightroom can auto-select the correct profile. If the metadata is ambiguous—common with some third-party lenses such as Tamron or Sigma—Lightroom may not know which exact lens profile to use until you first choose the manufacturer.
So the issue is usually not Lightroom “failing,” but the camera/lens metadata not being specific enough.
What you can do:
- Manually select the lens make when needed.
- Check whether your camera or lens firmware updates improve EXIF reporting.
- Save a Lightroom preset if you use that lens often, so the correction is applied more quickly.
