I have had issues with Lightroom failing to recognize Sigma lenses and automatically load the lens profiles.
I have several Sigma lenses:
- 105mm Macro
- 70-200mm
- 150-500mm
- 10-20mm
and two cameras
Sometimes the lens profile loads and sometimes not.
When it fails, I resort to setting the lens profile manually. I am confronted with a long list of manufacturers and once selecting Sigma, I am confronted with an even longer list of models. Invariably the lens I am looking for is way down the bottom and I need to scroll down on a very small arrow to find it. One slight mouse movement and the list closes and I have to start all over again.
It occurred to me that I don't need all the lens manufacturers in the list and I certainly don't need all the Sigma lens models listed. It would be convenient for me if I could edit the lists and delete those I don't need. I find no facility to do so in lightroom. So far so good. I did a computer search to find the folder where the lens profiles are kept. I found three possibilities.
- 1 C:\Programfiles\Adobe\Adobe Lightroom Classic\Resources\LensProfiles\1.0. This folder contains a nice set of folders for each manufacturer with each folder containing a number of LCP files for each model
- 2 C:\Resource Data\Adobe\CameraRaw\LensProfiles\1.0. Similarly, this folder contains a nice set of folders for each manufacturer with each folder containing a number of LCP files for each model
- 3 C:\USERS\Admin\AppData\Roaming\Adobe\CameraRaw\LensProfiles This folder contains only a file called pscashe.dat.
So far so good but which one? Being slightly adventurous, I navigated to the first two folders and altered the name of the ZEISS folder to "ZEISS- OLD" and "ZEISS - Even Older" respectively. The third location I left alone as it had no folders within.
Heading back to lightroom I attempted to locate the modified Lens profile folders. No good, all I could find in the Lens Profiles was the option for "ZEISS" Neither of the renamed folders appeared. I am none the wiser.
Why do I have all these folders?
Which one is Lightroom acccessing?
Is it possible to remove redundant folders and lens profiles from the system?
Is there a way to force Lightroom to properly identify Sigma lenses?
Any idea would be greatly appreciated.
