If you can see colored onion rings in images like this then it is pure halusination and not a real life phenomenon.
If you see rings here than it is most likely the lightening of the scene.
The onion ring issue can be seen in heavily stretched, preferably under exposed, images of a evenly lit white area. Taking images towards zenith in fog is an ideal excample.
False test. False alarm. No onion rings!

Edit: wrong word - should read imagination. Could not edit the post above.
Sorry - non native english one here...

I think he refers to the bokeh, not the Color Polygon issue discussed elsewhere. But I appreciate your sensitivity to the issue

Seems you are right - cats eye bokeh and such things. The title reads onion rings...I think he refers to the bokeh, not the Color Polygon issue discussed elsewhere. But I appreciate your sensitivity to the issue
And yes - we get blinded at times! ;-)
Am into astrophotography (not halusinations :-D) and have handeled my share of colored ortogonal shapes and onion rings - so this is a familiar landscape here.
The issue is real.
But it is not a good thing when an issue like this one erranously is used to explain all kinds of unrelated issues.
Love onion. Familiar with onion rings. Hate colored onion rings! :-D

So you are looking for the quality of the out of focus blur (bokeh).
The G and GM lenses are made for softer out of focus blur, especially the GM lenses.
Hope someone using the 1.4/24 mm GM will chime in and show some out of focus blur from light points in the dark.

If you scroll down, you can see examples of bokeh. There is mechanical vignetting which results in cat’s eye shape. Under certain circumstances it is possible to see concentric circles, however faint.

Nevertheless, most of the reviewers I’ve read say this is the bokeh champ among 24mm lenses.
Phillip Reeve arrives at pretty much the same conclusion.

Thank you. It looks like most of the pictures don’t have noticeable rings. There was one image near the end of Phillip’s blog post where it was visible. “The distance was a typical half body portrait”
At a 0.3m focus distance they go away. Also from Philip’s blog
Maybe I should make a post asking people what their experiences are with the 24mm
