I just got a Schneider - Kreuznach Optivaron f/1.4 6-70mm. I tested it out, it's very clean, appears to be fungus and oil free. Aperture opens and closes BUT the aperture ring is very loose.
I believe this lens came off of a Beaulieu 4008 camera and it's ring loose because when mounted on the correct camera features auto exposure. Is that about right?
I was wondering if there was a way to make the ring more secure. I like that it doesn't click and that it's smooth, but I'm worried if I set it to like f2.8 the slightest movement will knock it out of place.
Anyone have experience using these old lenses on cameras they weren't built for?
Btw, I'm using this on my BMCC.
