Thank you Chris.
The mods would not be for cine use, but still work. I have been looking at the images posted by Doug Peterson from the Schneider Cinelux 130mm f/2 and I am really impressed. It is a projection lens, so the aperture is fixed and there is no shutter in it.
I am slowly getting into more hospitality work and like the look of that lens for portraits, and feel it would be a good lens for product as well, if I could stop it down.
My idea would be to have an aperture installed into the lens and maybe a leaf shutter so I could use it on both a tech camera and SLR type camera.
Just an idea, not going to happen soon, but I wanted to add those businesses to my database for future reference.
