Re: Radioactive Takumars.

[graywolf]

Anyone have one of those Takumar 50mm/1.5's in their collection. Probably even 
rarer than the Pentax-A 35/1.4 that everyone says does not exist, but that I 
have held in my hands (it was in a photo store about '92-'93 $1000 mint/used). 
It may have been a prototype that escaped captivity somehow.

Isn't lanthanum slightly radioactive too?
