OMS OM-1 ORF files and LrC Lens Corrections

I've been editing photos made using my new OMS OM-1 camera. In one of the photos I noticed the horizon had a "dip" in it. I've not noticed this in other photos from other Olympus cameras I own (EM-1 Mark 2 for instance) using the same lens (12-40 mm f 2.8). I thought this was odd so I tried to correct it using the Distortion slider in the Manual tab of the Lens Correction panel. That helped but I would need to crop the image afterward. I undid the change and went to the Profile tab of the Lens Corection Panel. To my surprise, checking "Enable Profile Corrections" actually made a difference to the image. I was surprised by this since with my older Olympus cameras checking "Enable Profile Corrections" isn't needed as the lens profile of m4/3 cameras are automatically applied.

 

Here's a screenshot when editing a photo from the EM-1 Mk2

 

Here's a screenshot of the panel when editing the ORF file from the OM-1

 

Has anyone else noticed this?  While the panel shows the model and make of the lens, an Adobe support page (https://helpx.adobe.com/camera-raw/kb/supported-lenses.html) does not list any lens profiles for any Olympus/OMS lenses. Any idea of what is being done by LrC? What it's based on?

    I get this, which is what your first screen capture shows with an already rendered file e.g. tiff.

    All my screenshots are from ORF files.

    I think you should recheck that.

    Lightroom has never created lens profiles for Olympus m4/3 lenses. For my OM-D E-M1 Mark 1 with Oly lenses including the 12-40 mm f2.8.

    With an ORF from my camera, I see the following. The profile is automatically applied at import, it cannot be turned off.

     

     I downloaded an ORF from the OM to test and the following is displayed. The lens is the new 12-40mm f2.8 from OMD. The lens is automatically applied. Obviously created by the Camera, it just displays in a different manner.

     

    When you opened the lens correction panel did you do a manual change?

    No, I did not make a manual change. All I did was check the box. And when I check the box, the image changed. With files from my EM-1 Mk 2, I can check the Enable Profile Corrections box and nothing happens, as I would expect.

     

    Did you notice a change in the image you downloaded when you checked and unchecked the box? I have tried many images taken with the OM-1 and checking/unchecking the box and the image changes. This doesn't happen with other Olympus cameras. Interestingly enough, when a Panosonic LUMIX lens is used, this is what the panel looks like:

    Notice the Make of the lens says OM Digital Solutions, but OMDS does not make the LUMIX G Vario 35-100 lens.

     

    Just saying--something is different. Why does the image change when the Enable Profile Corrections box is checked and unchecked? It never happened before.

    It appears that the OM 1 is reporting the required lens correction differently and you are experiencing a different display in the lens correction panel.
