vignetting might be a real problem there, no?You deserve all credits for Navitar. I wouldn't even know it exists, if you wouldn't publish your brilliant post with images about it. Pity it wouldn't cover FF though, but it is certainly lens with unique rendering.
I don't have one, I have three nowI bought them on different places - two were in bundle from USA (eBay), and third has no sign Navitar, only TV lens 75 1:1.3 and was much cheaper (local store). In the process, I also bought Navitar 50 1:1.3, but I still didn't succeed to mount it on NEX, neither on OM-D (but, I am working on it), and 12,5mm, that I will try to put on Pentax Q. They all seems to have pretty much same characteristics.
