Indeed we could think these are Newton rings, but I can't see them with the naked eye, and I think No-X did not see such reflections too. I'm wondering how they could come here _________________ Cameras : Canon 5D, Pentax K100D, Pentax 6x7, Spotmatic

Not separated element, the pancolar has not glue between the first and the second elements.
That reflexions are present in some septon lenses. I saw it in old skopar for medium formart lenses too. Old people called it as "iridised lens" And not able to be fixed.
Casuality, or not, I never saw it in japanese lenses. Well is tru that I never try be a collector of them.
Incidence in pics? I don't know. Perhaps if you use the lens can eliminate the doubts.

Maybe this helps.
It is in German, but Google translator can be of help.
The effect can be due to uneven coatings on the lenses.
See:
http://www.mikrofotografie.info/Physikalische_Aspekte_von_Ring/physikalische_aspekte_von_ring.html
"Die Schichtdicke einer Linsenvergütung beträgt etwa 1/4 der durchschnittlichen effektiven Lichtwellenlänge, entsprechend etwa 140 nm (Netzwelt-Lexikon, 2006). Ungefiltertes Weißlicht mit einer Kohärenzlänge von etwa 1000 nm kann daher Interferenzerscheinungen an Linsenvergütungen hervorrufen, wenn die Vergütung ungleichmäßig aufgetragen ist und deren Schichtdicke geringfügige Schwankungen zeigt. Es ist bekannt, dass ungleichmäßig vergütete Linsen Newton-Ringe zeigen können (Netzwelt-Lexikon, 2006)." _________________
