The 50/1.5 lens is the earliest among the 3 lenses, which is always blue coating same as the Canon lenses at same era.Agreed it completes the set. One thing I immediately notice from Mr. Li's photo, is how bluish the coatings are in the 50mm, compared to the later amber-colored coatings, on the later lenses.
The photos in this thread have convinced me as to the worth of the lens:

My Canon 50/1.5 has brown coated glass, the same with my chrome 50/1.8. AFAIK Canon switched to the brown coating around 1954-1955. The black lenses with alloy body came a bit later, 1957-1958.The 50/1.5 lens is the earliest among the 3 lenses, which is always blue coating same as the Canon lenses at same era.

I and my friend have collected quite a number of 50/1.5 and 50/1.8 Chrome before, all with blue coating (with some amber coating for some of them). First time to know that all amber coating was available 😎My Canon 50/1.5 has brown coated glass, the same with my chrome 50/1.8. AFAIK Canon switched to the brown coating around 1954-1955.

You can add Serenar 50/1.9 collapsible, always blue/purple.
Note that several lenses exist in many versions. The 35/2.8 for example had blue/purple coatings in the first versions (all chrome, 34mm filter ring), then coatings became amber (black and chrome versions, 40mm filter ring).
Does the coating color make a difference in performance with color film?
