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 don’t see any rings in your sample.

please note the four corners of the image and how there is kind of a BRIGHT ring around it

Turn off lens correction. I've seen this ring pattern before happen on certain lenses.

really? so if i turn off lens correction, this will go away?

[deebatman316]

Yes certain 3rd Party lenses don't work correctly with Canon's lens correction software. Sigma lenses are famous for this. Turning off lens correction fixes the problem. But the problem is much worse than yours.

hummmm....well i would need to give it a go. I was playing around with those settings. I think they were turned off to begin with but I will check
