Recently switched from GH5 to Canon R5. I just received the new RF 14-35mm f/4L lens and noticed the RAW images show extreme barrel distortion and vignette. I did some research online and apparently this is normal. read a suggestion to enable "Distortion Correction" within camera, but this option is grayed out and cannot be enabled. I checked my firmware and it's at 1.3.1, which I believe is the newest one. Another suggestion was to correct it using "Lens Correction" in Lightroom, but the lens is not showing up on the list of supported lens. I assume this is due to the lens being really new. I would really love to get the camera to process this correction within. Never ran into this problem with my GH5. Is there a solution?
