You will need 800mm of bellows to focus at infinity, or approximately 32 inches, and much more for shooting closer subjects than infinity. Your lens may not be adaptable to a shutter, best to use a behind-the-lens shutter such as a simple Packard, or a camera with a behind-the-lens shutter system such as Sinar.
