Those lenses have good metal encasing and the radiation is so small that there’s no real problem except the lenses start to turn to yellow with age.
- penagwin 7y agoMy understanding is that exposing yellowed lenses to UV light will return help it un-yellow. That type of glass was mostly only used in older lenses - which with the right adapter they still work great on modern cameras!
