The Tamron 17-70mm lens with the X-T4 produces a strange double vignetting, which is most noticeable when photographing the sky. It appears at aperture f2.8 and is most noticeable at 17mm focal length. The effect disappears when the aperture is set to f4 or higher.
I hope Tamron service will fix it or replace it with another lens.
I leave some examples in jpg.

Do you have a polarizer or any other filter on there?

has no filter
