Some contemporary M lenses have still the same bicolor coating.

I personaly doubt that an multicolor "MC" coated lens is by definition
better than an bicolor coated "SC" lens, my experience is, that the type
of lens (number of elements, type of glass used...) is more important
for performance than coating.
Generaly I´m mistrusting the meaning less techno advertising blah blah,
if an lens has MC, ED, IF, aspherical, floating elements and so on. The
technical details should be left to the designer/enginer creating an
lens. I think it is imposible to deduce image quality from the technical
means used in the lens. The user may only see the resulting image
quality, which has normaly such a high standard, that it is dificult to
carry out meaningful do-it-yourself lenstests.
