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!

It sounds like the Tokina is made for crop sensor cameras.

Greetings,

I don't follow Tokina's products too closely.  Can you confirm the model?  I thought they made a 16-28 for full frame?  What brand adapter are you using?

I suspect the R6II is operating in crop mode because it can't determine the model of the lens which is mounted.  What to check.  Try changing from crop to full.

It's made for full and crop body

Tokina 16-28mm, it's made for full frame. 

The mount adapter is canon

Have you looked at the crop mode setting?

As far as I know that it's a crop sensor lens. If you want to use it you need to switch the camera to crop mode.

Thank you but it's not on normal mode. I suspect my old lens is not right. It's weird. 

The image is cropped and there is a flair around the image.

Can you please provide the full name of the lens in question. If the lens was really designed for Full Frame. It would not produce vignetting on a Full Frame camera at all. Canon's Full Frame DSLRs don't have an APS-C crop mode either. Canon made a separate DSLR crop sensor mount called EF-S. These lenses won't mount on a Full Frame DSLR or EOS AF SLR.

If it is a cropper, then all he'll get is 9.3MP from his R6II
