Hi there,
just realized the lens correction profile for Ricoh GR IV in LR version 15.0.1 is wrong in terms of vignette correction. It leads to significantly oberbright edges. Applying the GR III profile seams correct.

Hey, @JJ.72. Welcome to the Lightroom Classic Community. I'll share this with the product team for review. 

 

Could you share a few screenshots showing the behavior and a few sample images where this does not work as expected? 

 

Thanks!

Hi @JJ.72, thanks so much for sharing the screenshots and the sample file!
I’ve passed this along on Sameer’s behalf to the rest of the team. They mentioned that, based on the image, it’s hard to say the corners are truly overcorrected. One thing to note, the comparison is between the GRIII lens profile and the GRIV, and those lenses aren’t the same.
Could you check if you can reproduce the over-corrected corners using flat field images?
Thanks!
Alek
