Interesting, Joel. The block diagram helps to understand it. I wish someone would post a photo of the spots.
A local dealer here had an M-Rokkor 28/2.8 for sale that had a very uniform circular donut pattern of small and smaller round dots, that looked like it could have been between elements 2&3 from the front -- sort of like the dot pattern on a CLE shutter but very symmetrical.
I'm still trying to work out what that might have been -- they offered to let me try the lens out but were asking far too much to consider buying it.
Thanks for the photos, Petar. They tell me much more than discussion and it's a fascinating look.
