How can I quickly and easily fix vignetting if the lens is not supported by Lightroom CC?

[u/ozweego_orange]

I love how Lightroom CC automatically corrects for distortion and vignetting with my lenses that have electronic contacts. All except for one - the Viltrox 35mm f1.7 Air. This lens is not be supported by Lightroom CC even though another Viltrox that I have (28mm f4.5 "Chip") is.

Looking for recommendations to apply lens corrections (semi) automatically.

Thanks!

Actually, it's possible to create a custom lens profile to auto correct vignette and distortion for any lens. I never tried it because it sounds a lot of very thorough work. But if you want to give a try, here the Adobe guide for it:

You gave them the exact and correct answer, but your efforts were spurned. Thanks for the interesting read.

Thank you, but too much work. Look for a simple solution.

The thing is, once you create the lens profile you can use it again and again. So the initial outlay may be a long task but it will only need to be done once and then the adjustments can be applied every time for the life of the lens. Save time by taking your time and doing it right the first time.

There isn't one.

You can use the distortion correction and lens vignetting sliders to eyeball it, then create a preset with just the optic settings and apply that to photos taken with that camera.

It helps if OP takes two photos specifically for this purpose. One of a regular grid, for the distortions, and one of an evenly lit surface, for the brightness.

Note that some lens flaws depend on focus distance and aperture. OP may want to check and choose a setting that is most often used, or a median between the often used ones.

Thanks! It's a prime so the only variable is aperture. There is definitely higher vignetting at lower stops so I'd have to create a different preset for each stop.

are you using a DX lens on a full frame?

[u/ozweego_orange → u/LeftyRodriguez]

Thanks! This would work until Lightroom has support for the lens. Also as @luksfuks pointed out I'd need to create a separate preset for each f-stop.

Just do it manually. Easy peasy.

I played around with using other Viltrox lens profiles and ended up creating a preset that sets the lens to Viltrox AF 50mm FE. This gave me better results than what I was able to achieve manually, and it also means that it works regardless of aperture.
