UV treated Radioactive lens vs. Non UV treated radioactive lens. (S.L.E.)
Another "Stupid Lens Experiment" episode. This time around we get to compare a old radioactive Super Takumar 50mm F1.4 that has it's glass turning yellow/brown with another copy that has its glass UV treated and clear. Enjoy.

Thank you for the test. My Takumar 50/f1.4 and Takumar 55/f1.8 are both radioactivated, the 1.4 being yellowed heavily such that it is visible as soon you remove the lens cap. I choose however not to treat them. I have several other 55&55 lenses and it is okay to keep the charm of these lenses.
