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.
