I have a picture of some geese flying over a plain blue sky taken with a Sony A1+ 70-200mm f4 G II.
All the autoable settings are on auto, including vignetting. The result is white corners / edges. Switching off Auto Vignetting, which defaults to 100, seems to give a much better result. A setting of about 50 is still OK. This is the first time that I have noticed this phenomenon. (7.0.3)
So I don’t know whether it is the profile for the particular lens, or the interaction between vignetting correction and, eg, clear view or, indeed, the creative vignetting setting that I also have set (to -10).
