I cannot say for others, however there is a 1.4 Mutar shift lens that is for use with the 40mm Distagon. I forget all the details, but, basically, the magnification is a compromise necessitated by the requirement of having an image circle large enough to cover the negative when using the amount of shift afforded by the lens. Looking at the Mutar, using the 40mm, you get a maximum of 16 degrees of shift with what is, effectively, a 56mm lens. For that format, that is, actually, quite a bit of shift.
