Simmod ARRI PL to Leica L Cine Pro Adapter

I own (and love) my newer Blackmagic Design 6k camera with full frame sensor and Leica L mount. I also have a number of wonderful new and old Zeiss PL mount fixed cinema lenses. (18mm - 200mm) So when I saw this adapter for sale at , along with a good review of it, I took the plunge. I am not disappointed. With this adapter, a fairly heavy Zeiss lens with ARRI PL mount, like their CP.2 25mm for example, hangs off the Blackmagic camera with no discernible wiggle. The lens goes on and off a bit tight, but hey, that's what I wanted. It looks great too, with excellent machining and black surface coating. Note that nothing to do with this excellent adapter itself my oldest 1970s vintage Zeiss Super-16 lenses, while still producing great images, do vignette at the image corners, from 9mm to 16mm when the Blackmagic camera is set to FF 6k, exactly as I expected. But I could not have verified that without this Simmod adapter. Note also that simply changing the Blackmagic camera setting to capture a more restrictive Super-35 4k size, allowed more of my older PL mount Super-16 lenses to be used. The lens coating on those older Zeiss is not quite as nice as the newer CP.2 or CP.3 but still hard to see much difference in most lighting conditions. Again, this Simmod adapter allowed me to test all this.
