The lens used for the pictures above shows some 'natural coating' a colored sheen often seen on very old uncoated lenses. This kind of ultra thin oxydation of the lens surface works exactly the same as coating, so leave it as it is, never try to remove it!

Erik.

The story goes that when it was noticed that old uncoated glass developed this sheen over time and the connection was made between this and improved image quality this is what first gave scientists (I think they may have been employed by Zeiss) the idea of artificially coating lenses to see if it produced the same effect. The rest as they say is history. I am not sure if this is an urban myth.

I am not sure if this is an urban myth.

I think that some intelligent optician at Zeiss saw the effect and he or she understood that because of the coloring of the sheen more light must go through the lens instead of being reflected. Colored reflection means that less light is reflected. Light = energy and that will not disappear.
