Lightroom 6: Creating lens correction presets with new camera

I just got a new Canon G7X mark II as my street camera to replace my Canon S95 I have Photoshop CS6, and Lightroom 4, but LR4 could notrecognize the files, so I upgraded to LR6 (6.8). I had a preset for importingS95 files into LR4, which I used for my first tests, until I can create a newone for this new camera. And, I also converted the CR2 files into DNG files. Myquestion concerns the Lens Correction profiles in the Develop module. Along with some basic settings, the preset was also set tocorrect for distortion and chromatic aberrations for the S95, so in LensCorrections I had it set to Enable, and the set up is Custom. However, below itit says “Built in lens profile applied.” So does that mean the embedded distortioncorrection overrides the preset, which in this case is for the S95? I don'twant to undo what LR6 seems to be doing on its own properly.

I want to start building a new import preset, which means Iwould not want to have the S95 distortion setting as part of it. But, if Iselect Default or Auto to turn it off, LR6 now tells me that it can’t find thatG7X II profile, so no corrections are applied whatsoever, which is not what Iwant. If I look under Model, the G7X is not listed, just the older S95. So nowI am unsure what is the best solution to creating my new preset.

Thanks.

Hi,

The Canon G7X II uses opcodes to automatically correct lens aberrations in-camera. You should modify your preset for this camera to NOT check "Enable Lens Profile Corrections" because that setting applies only to external lens profiles which are not required for this camera. Leaving "Remove Chromatic Aberration" checked on may have no effect or (depending on the scene content) could improve upon the CA correction applied by the camera.

Regards,
