The 24-105mm is my main lens on my 5D MkIII, but I use DxO Optics Pro to correct for geometric errors, CA, vignetting, etc. DPP has DLO built into it and you can add it into Lightroom. It looks to me like you've already discovered DLO, but, if not, check it out.
I have not heard of (or used) DLO but it seems worth checking out. The image was not straight out of the camera as I cropped it. This is what it looked like straight out of the camera (just resized it):
