radioactive canon ltm lenses?

[ghost]

were any canon ltm lenses radioactive? i just had the thought that a canon 28/2.8 i have might be yellowed from radioactivity instead of being deprived of its coatings.

If you really want to know, you could expose some fast film to it overnight, then develop. Black specks indicate radiation....

I guess you shouldn't shoot from the hip with those! Nice topical avatar Bryce.
