Lenses designed for SLR cameras can be easily adapted to any mirrorless camera due to very short flange focal distance of this type of cameras. Of course I do understand that some people may not know this, but I still think that it makes no sense to include mirrorless cameras in the adaptation table.
In fact, I am thinking about removing this section, since the popularity of digital SLR cameras among amateur photographers is constantly decreasing, and professionals do not adapt vintage lenses for commercial work.
I think that this lens should not be radioactive. My point of view is based on the fact that only lenses produced from the 1940s to the 1970s were radioactive. Of course, not all of them, but only those that used thorium oxide as a component of the glass. And this X-Fujinon 50/1.9 FM lens was introduced around 1985, so it should be free from radioactive materials. X-Fujinon 50/1.9 DM lens introduced around 1980 also should not be radioactive.
