>>Remember, Pentax *invented* coated lenses, I remember reading that the value of lens coating was gradually realized by photographers over time based upon a natural phenomenon: 'Blooming' of micro-organisms across the glass surface of a lens, if done just right, seemed to increase light transmission and reduce flare. After a while, certain vintage 'bloomed' lenses became especially valued, until manufacturers were able to develop a commerical process. In other words, the value was discovered by photographers, rather then being invented by a manufacturer. Anyone can verify this?
