I was wondering if anyone else was using the Sony FE 100-400 GM lens, preferably on a A7III body.
I am having issues with vignetting that I can not get rid of.
I have tried narrower aperture (up to f/40 lol) I have tried turning lens shading ON in the body, I have tried using the lens profile correction in Lightroom, vignette reduction in Lightroom and in Affinity photo, yet, I cannot get rid of it and I am getting "vignetting not allowed" rejections.
I am currently speaking with Sony Pro Support and they will most likely want to take a look at the lens, in the meantime I was wondering if this was a common issue with that lens on a FF body.
It's one problem I never had with my Canon
