Super-Multi-Coated in this lens is
At the time of its release, two-layer lens coatings were the norm for other manufacturers.
This was the first time in the world that a lens was coated with a maximum of seven layers.

I would like to find differences in color, backlighting, etc.

Why don’t you get into the world of vintage lenses!
