Sony 24-105 at 105mm/f4 dark ring

[Kasboh]

I noticed a strange behaviour of my 24-105 at 105mm f4. In some scenes it has a strange dark circle.
Can someone who has this lens take a picture of a white wall at 105mm f4 and post a raw file here or open in lightroom and crank the dehaze slider.
below is how it look on my lens. It is not a normal vignetting as it a has a dark ring

Thanks Jeff, your image looks normal to me with normal vignetting
