[Leica] Lens color cast

[kanner at acm.org (Herbert Kanner)]

Apologies for mental lapse, and I hope I get informative responses. I 
intended to write "Summicron" and for some reason that would only be 
known to my psychiatrist if I had one, I wrote "Summitar".

>The two lenses are Summitar M, and state on the front: "Leitz  Lens

>It is not a problem. The color cast is easily correctable in

>about the glass in one of the lens elements, or has the cement on
>compound elements yellowed through age? When I looked through the
>lens at a white area, I saw fully uniform yellow.
