The extension bellows are all nice and good for macro work, but I'd bought it in hope that I would be using it for working pictures with vertical shift at 50+ feet (or infinity). These bellows are not very flexible, so I do not have any flexibility at all with shift/rise at infinity for fear of tearing them. Is there any way to replace these bellows, with a finer more flexible set? Is there something I can do mechanically so that I game it such that, infinity is one inch in front of body, rather than none? I guess this is why view cameras have BOTH a rear and front standard, and not just one.
