Amazing ....Takumar Lens Treatment for Radioactive Yellowed Glass

I was just going though some Vintage Lens Repair information on the Internet and discovered THIS.
I cannot believe someone would actually do this to a lens. Don't think I want this Moron working on Anything I own.......lol.

After such repair, the affected lenses will surely NOT be able to produce distorted colours on images... Fortunately, I don't have any of those old lenses around to be tempted...

Overkill. Ball peen hammer more than sufficient for this repair.

Oh dear, it's this guy. I'd almost forgotten about him. What a sad end for a great lens.

I thought that this could be cured by exposure to UV. Alternatively he could have just asked the seller for a refund

Mind you It is a terrific tribute to the construction of these old Takumars, It actually seemed to hold up pretty well. I have a broken nikkor 18-55mm - I doubt that there would be anything left of it after such a beating!

Does seem like a terrible waste though.

I believe this method can also be used for fungus, sticky diaphragm and other lens problems.

I'd rather see it "blowed up real good" by Big Jim McBob and Billy Sol Hurok on Farm Film Report...

Too much like hard work. I think I will just leave mine laying around in the sun.

Those lenses which are described as literal fungus farms, with stuff emerging from every crack, probably are justifiable candidates for that. Alternatively you could sell them to this guy. (The book is a delight for kids aged six to ten, even if the descriptions of Bogey photography would horrify most of us.)

Well-quite brutal solution

And all you need to get rid of yellow cast on lenses in most cases is just nail drying UV lamp and some time

Digitalis, I will happily accept any 30 1.4 EX or HSM in K-mount that you want rid of. I will even cover shipping and such.

This is an honest request to help me help you.

You Really DO Have it in for that Lens !!!

This guy should go visit his doctor for lung cancer diagnose every year after he did that: he smashed the radioactive glass and produced so much radiation dust in the air. From the photos, I can hear his heavy breath; and he inspected the smashed lens quite closely. same as the Curse of the Pharaoh, he received the final fight back from Takumar

I think that was just a joking, the lens might have other issue. At least I took it that way when I saw the page years ago.
