This conversation has been merged. Please reference the main conversation: Lightroom/Camera Raw: Disable built-in lens profile

I recently purchased a Sony A7R2 and rented several Sony FE lenses to evaluate which ones I want to make part of my kit. While comparing some shots in Lightroom 6.7 I noticed a little notice in the "Lens Correction" tab of the Develop Module.

This is a little surprising as I had already turned off all three "Lens Comp." options in the A7R2 menu even though I only shoot raw. Additionally because I am shooting raw I was fully expecting that no lens compensation corrections would be made unless I enabled them in the Lens Correction tab.

Now I find that sometimes Adobe apparently is using lens correction profiles imbedded in the raw files by some camera companies, Sony, Fuji and Olympus to automatically apply some. corrections. 

In the case of the three FE lenses I have tried so far they always seem to be corrected for chromatic aberrations. This is always applied even though I turned this off in camera and have not checked it in the Lens Correction tab.  For some other camera/lens combinations distortion and/or vignette corrections are unilaterally applied by Adobe.

It has been pointed out to me that some of these corrections are an integral part of the camera system, that some lenses were in fact designed to rely on such software corrections. While this makes a good case to make these corrections the default action I don't think that they should be mandatory.

Some how this did not make it into the Lightroom discussion area when I originally posted.

Most likely, you forgot to add "Photoshop Lightroom" as one of the product categories, and a moderator added it for you.

Hi Louie,

Per request from Sony, Lightroom will enable the external lens profile automatically for raw files if the lens comp settings are enabled in the camera and an external profile is available in the version of the application you are running. The external profile corrects for geometric distortion and vignetting only. The chromatic aberration correction is baked into the raw file using opcodes that cannot be disabled in Lightroom.

If you wish to disable the external profile by default, you can set a new lens profile default (with it disabled) for each lens/camera combination.

Regards,

- Chris

Thank you Chris for the explanation.

The interesting thing is that I could see the CAs in the in-camera preview while taking my test shots the other day, However, as you noted the CAs in the raw file gets corrected regardless. It seems that Sony will allow you create in-camera JPG images without the CAs being corrected yet always correcting them for raw files. This appears to have been confirmed by testing shown here https://joerghaag.com/2015/03/29/in-camera-lens-compensation/

I think that this is bug in Sony's firmware. I am using the latest ver 3.30. Maybe you can also bring this to Sony's attention.
