This significant SMC coatings improvements over the years myth needs
debunking. Original uncoated lenses
( pre WWI era ) reflected about 5% of the light on each air glass

Single coating introduced in the 1940's which was very noticably better
got that reflection down to
about 1% per air

NO, I am not saying that improved SMC coatings may never give any
visible flare performance over the original SMC coatings of 1971, but
it is only going to be visible on really high element count lenses if
at all, certainly not on
