I've recently fallen in love with my new Canon 24mm tilt-shift lens but to my chagrin, I see that Lightroom does not have a lens profile for it! Do you know how I can install one or get a custom profile? I'm using CC 2017.
The reason you can't find lens profiles for any tilt-shift lenses is that correction profiles won't work for these lenses as the software has no way of knowing where the center of distortion is. Tilt or shift movements aren't recorded, so any values would only work with the lens centered.
You can make lens corrections you think are necessary manually but many people would argue this lens doesn't require any corrections.
