The lens is a pig to clean like the MC filters I use.
I have an earlier '79 5cm E and it is similarly difficult but butt ugly all black plastic.
I re-checked my Series E 75-150mm leafleat and it actually says "Multilayer Nikon Integrated Coating (NIC) on the air-to-glass lens surfaces helps to minimize ghost images and flare..." It is dated 80.3.E.
So, I stand corrected. There is now document evidence of multi coating.
