Danger- radio-active glass
This is the Carl Zeiss Jena Pancolar 50/1.8. It's probably the most radio-active lens I own, judging by the amount of yellowed glass. Photographed with another radio-active lens - a Yashica Yashinon DS 50/1.7, and a Raynox M250 magnifier.
There's quite a debate on the web about how dangerous radio-active lenses are. Personally, I don't believe they are too harmful, unless you spend all day and night with them....
