Greetings Larry .. I have been researching about vintage lens; their mounts, in different formats. and its possible use of modern cameras for digital cinema with different sensor sizes I have the answer ... That teleconverter is for Angeniux 16mm / super 16mm lenses, not for 35mm lenses. I think the acronym AR that A = Auto R = Distance reference. You don't need a rear focus ring. I have that teleconverter with Angeniux 12-120 lens That is being restored. I still don't do the field tests. It should work with cameras with the micro sensor size 4/3 APS-C corresponding to 16mm / super 16mm. I hope I could collaborate.
What does the "AR" of Angenieux AR lenses stand for?
