I was teaching my daughter about aperture and depth-of-field by showing how Christmas lights get less blurred out by stopping down. I used her dolly as the subject. I was using a 50mm 1.2 on the R6, but later found that any faster lens on the EOS R body also does this. I did not try on the 80D...
Camera was on a tripod. IS and IBIS were off. I tried with and without a B+H UV filter. I was in manual mode. Anti-flicker on or off, same result. Mechanical or EFCS, no difference. (In fact, I could see it through the EVF before taking a shot.)
You can see in the photo the type of fringing I mean. I don't know that it can be properly called chromatic aberration?
When viewed without zooming in, this fringing gives a "bad green screen" type of effect.
A glass also shows a more ghostly type of the same effect.
I tried searching, but couldn't find anything on point. (Google asked, "Did you mean Christmas lights fingering?")
Stopping down reduces and eliminates the effect as the whole subject comes into focus. It's only the out-of-focus area of the subject.
