Found it! Not a great screen shot of a PDF but it will give you the concept.
No, that is not what I have. Later model Bronny's have a lug with a hole in it, similar to what you find on many Nikon/Minolta 35mm SLR camera's, so in reality, I should simply do what has been done on those camera's. The round rings that came on the camera obviously arent up for the task. The Triangular jobbies should do the trick (+ a standard Pro version of the optech)
Once again, Minolta to the rescue. A Nikon probably would have just let it drop
Nah, Nikons have a sentimental attachment to Bronicas, as the old ones used Nikkor lenses. Also, Bronica attach their lenses counter-clockwise, like Nikons, so there's that, too. And Nikon made LF lenses, too, so they're not the 35mm chauvinists Canons are.
I know, some Canons are friendly, but others are just so insufferably arrogant!
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
