re donuts out of mirror lenses: from my experience, such donuts appear for bright points and objects in the out of focus background mostly. How can there be donuts in th eevenly blue sky? Or in the dull foliage. So none appear here.

They also seem not to show on bright spots in the out of focus foreground.

So I only worry about specular lights behind the plane of focus.

Any one else to support my observations? A theory of this donut behavior?


I basically agree with what you are saying. Here is the "classic" example of "specular lights behind the plane of focus" . . .

Haven't had to much of this behavior . . .
