Yes, the Yashinon-DX does not use Thoriated glass, but the DS version does use it. Also, all 4 versions of the Takumar f1.4 are radioactive. The original Super Takumar 50mm f1.4 8 element version, the next one was the 7 element, Super-Takumar 50/f1.4, then came the Super-Multi-Coated Takumar 50/f1.4 that is probably the most radioactive of the four and lastly came the S-M-C Takumar 50/f1.4.

Great video.
I recently good a Yashinon dx with focusing is off to where infinity is at 1.2m but it also allows for infinity on Nikon cameras.

It sounds like the lens has been modified for use on Nikon bodies.

My Yashinon 50mm 1.4 DS is definitely radioactive.

Takumar was noticeably sharper.
