Tokina Mount Adpater creating a ring on EOS R6 Mark II

umairlooms — Fri, 23 Aug 2024 12:29:05 GMT

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.

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

If it is a crop lens then how would the OP not have vignetting on the 6D Mark II. It is a Full Frame lens.

Can you post a sample image that shows the issue?

Do you have another camera to test with this lens? Test without any filters or lens hood. Thanks!

Is this your lens?

Re: Mount Adpater creating a ring

I am almost certain it is the lens in the image I posted, which is an older full frame lens. Even if it were made for crop sensor bodies, it would still use the full frame EF mount. I cannot think of any third party manufacturer that actually uses the EF-S mount when the EF mount is sufficient. Why make two mounts just for Canon bodies?

I have asked the OP to post a sample image of the issue, as well as the lens on another body without a hood.

Appreciate the response. There is a bit of a time difference. I'll post a photo of the lens we have in the office and the result we are getting. My boss is pissed at me and it's been a very distressing day. I'll surely update you in the morning . Thank you

We don’t need to see a photo of your lens. Just confirm the full model number.

Wewould like to see a photograph that shows the issue, so that we can better understand your issue.
