Tokina Mount Adpater creating a ring on EOS R6 Mark II

[umairlooms]

NEED HELP!!!

I bought a Canon R6 Mark ii and had to buy a mount adapter to use my Tokina EOS lens 18/28 which I used to use on my old Canon 6D mark ii.

Now when I photograph, there is like a ring flair on the photos? WHAT TO DO NOW!

I noticed the the “ring” at the corners of your photo. It’s probably being caused by noise and image processing by the camera. Many Sigma lenses exhibited similar issues. 
Sigma corrected the problem by updating the lens firmware on lenses compatible with the Sigma Dock.

You cannot update your firmware. I recommend disabling all in-camera image corrections.

thanks. Yes we already disabled them but the issue still exists. I had no idea that this issue existed. 
Would having a Tokina Adapater resolve this? or Am i just being too optimistic
