Re: Samples from my cleaned 28mm f/2.5

Because UV doesn't easily get to the radioactive element (it's deep inside the lens), it takes a long time to UV clean. Even mine isn't perfectly clear. It will take months on a windowsill, and/or weeks with a UV lamp, but it will get better optically as it gets less yellow.

I guess I'll just starting storing it on a south windowsill for a while. I'll just need to clean it before using.

Do you know if I am better off pointing the front or the back of the lens up?
