Thanks Simon, could you explain what is different about the mounts? From what I have seen, these are both C-mount.

I've been looking for some information on the differences in the Schneider-Kreuznach Tele-Xenar lenses, specifically the 150mm f/4 C-Mount which I have seen in both a "Cine-Tele-Xenar" with a black zebra design, as well as an all-silver version that doesn't carry the "Cine" label, but looks to have notches in the lens barrel for something similar to a reglomatic control unit sometimes found with Beaulieu cameras. Can anyone shed some light on what is different about these 2 designs? Are they just separate runs with updated designs? Would either work fine mounted to a Beaulieu R16/4008/etc, or are there major differences I should be aware of? Thanks for any insight!

Hi everyone, I recently got a Scneider-Kreuznach UWL III ultra wide adapter to use with my Beaulieu 4008 ZMII and was just curious as to the proper configuration with the macro setting. When I pull the macro lever on my Schneider Optivaron 6-66mm 1.8 all the way down, it's impossible to focus on anything no matter how close/far (this is also the case without the wide angle adapter attached). I can get things into focus when pulling the macro lever just slightly, but it doesn't seem to be super secure in that position. I'm currently using the lens without the reglomatic zoom control unit. The macro lever has some friction initially, but then feels loose/smooth until it's pulled all the way down. If something were to bump it or I accidentally touch it when adjusting the iris, it could shift things out of focus pretty easily. My question is, is this normal and that's just how I need to go about achieving the fixed focus with this adapter, or should the macro lever on my lens be behaving differently? Thanks!
