P: Disable built-in lens profile

I don't understand these merge things. But before I write this topic, I used to read the mentioned ones, but the answers didn't seem (as far as I understand) adress my problem. My problem is

1. beyond Olympus only, and requires a reneral solution
2. has nothing to do with Sony external profiles

What I'm talking about is simply about built-in profiles, whatever the brand. If LR knows how to apply them, it should be able not to aply them.

Now I'm quite confused with all these messages. Nobody has a single chance to understand anyhing, and the bug will never be solved. Anyway, I've already switched to DXO Photo Labs just because this issue. At least, DXO let people use their raw files.

Updating the lens or camera firmware will have no effect on whether a lens aberration opcode is applied. Lightroom and ACR always apply them if they are present. There is no way currently to disable this in either application.

Here is an update:

I have since updated to 4.00 firmware and no change in behavior.

It is inconsistent that my camera offers the option to disable chromatic aberration , distortion and vignetting  and that the resulting "opcodes" in the raw file cannot be overridden in Lightroom. 

When you say "baked in" do you mean that raw file is already modified? How can that be if the in-camera setting is turned off. I would like to hear a better explanation of what is going on here.

It is a little annoying that when this topic got merged my original response was dropped. 

So here it is again:

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.

Hi there
I too have been miffed about Auto lens profiles being applied in both Lightrooom and Photoshop; with absolutely no way of disabling it.
I shoot extensively with an Olympus 8mm lens so very often I am wanting distortion.
At last I discovered Olympus Viewer 3, you can TURN OFF lens information on Olympus raw files.
In RAW2 edit section / Distortion Correction / Manual -uncheck the "Use Lens Information" and adjust manually the distortion on a plus or minus scale.
What a brilliant way to dial in your preference as you intended, I rather think it may only be for Olympus users?

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.

I would add that :

• It is not a huge work : no new algorithm, no new dialog
• It really ruins compact gear when used with LR
• It does not change anything to the existent : nobody will complain because it doesn't change anything for existing pictures and default behaviour of LR

Another example (not a landscape)

This is what you get with the standard profile : people on the side look fat because of the strong streching induced by a rectilinear projection.


This is what you can get when you disable the lens profile : people look much more natural and the image is wider than 24mm (like having a better lens). I cannot see an obvious drawback not having lines totally straight in situations like this one.


A software should permit the user to have more control. LR forces the user to use a profile, while using a profile should be a possibility offered by the program. Profiles can be enabled by default, but we would like to disable them at will.
