statement bothered me when I first read it so I did a check of my 50 f1.4
whcih is marked MC. The coating reflection is yellow and purple, no green,
yet the lens is clearly marked as Multi coated! I suspect that there are
differing formulations and coatings, possibly the yellow/purple is an early
MC?"
>>> Well, I guess it could still be multi-coated. Seems like I read
somewhere (FAQ, maybe) that a consensus had been reached that
_any_ green reflection was MC and yellow/purple was SC.
Have you owned your 50/1.4 since new?
Any chance it has a different front element or ring than the original?
(just a thought)
I'll take another look at mine and see if I see some green. I'll take
special note of the internal elements if possible.
Anybody else have non-green reflecting lenses marked MC?
