We were speaking of the hardness of the glass, not of the coatings, Eric.
And, in any event, the era of soft coatings pretty much ended for the major

as hard as is the glass.


We were speaking of the cleaning of lenses, many of which have coatings from the 50s. Some of the coatings on 50's F&H cameras are notoriously soft and prone to scratching...
