Lightroom Classic: Z6 2 Vignette
Got the Nikon Z6 II. In Lightroom Classic (desktop) 10.2 all images with lots of sky (bird in flight) appear as a medium to high vignette. LRC accepts the NEF OK, but I suspect it does not have a camera profile for the Z6-2. Using the Nikon 28-300mm FX lens with Lens Correction on (or off) has vignette. A Sigma 150-600 lens with Lens Correction looks good. Both use the FTZ adapter. If I apply Sigma 12-24mm F4.5-5.6 EX DG Aspherical HSM to the Nikon 28-300 it looks pretty good. Maybe over compensating a little, but lots better than original.
Both the Sigma 150-600 and the Nikon 28-300 look normal, no vignette, on a D500. I have many DX and FX lenses, all look good on the D500. Out of the half a dozen that I have tested, all have vignette on the FTZ/Z6-2. This indicates to me that it is not a lens/Lens Correction issue, but a camera profile issue. Is there an update with camera profiles due to come out?
