Radioactive not sure if 50 or 55
Lens: not sure Camera: K-3ii Photo Location: NC 
Posted By: condor27596, 10-28-2017, 07:05 PM

Check this out. This is the manual radioactive lens. I wear bifocal contacts so I have a lot of trouble focusing exactly. It could be even sharper. I removed the slight yellow tint.

Does anyone know what is the kind of lamp to use to remove the yellow? I almost got it all out but I broke the bulb and now I forget. Thanks.

This will be the magnetic calendar pic this year.

The generic answer is that you need some kind of UV light.

I just put mine out in the sun.
By the time I heard I needed to worry about heat, which could cause the lens elements to become unglued, the lens was clear and the glue had held.
