You can use the Rodenstock 35 mm and also the 38 mm Super Angulon with all backs, but when you want to shift there is a problem with 80 mln backs, that the CC can not be handle by the software. The same problem is with apo digitar 35 mm. The 38 mm handle it better than 35 mm, becouse the distance between the lens and the chip is at 38 mm SA bigger becouse of the spacial lens construction than at 35 mm lenses. Shift till 7-8 mm is is OK, sometimes more, but about 10 mm the software does not work, you get edges dark and out of color. This is only with 80 mln chips, all other back have not these problems. If you use classic backs like Phase one 45,H3D39, H4D50, and others you can shift without these problems, but the sharpness at the corners will become poor when shift mor than 15 mm and you must use app16, or maybe more.
Second- most camera systems have problems by using 35 mm lenses, most of tham does not allow to use 35 mm with a slidding back, only with the direct adapter.For example Arca swiss can not do it, but cambo Ultima can, even with the sliding back. For using 35 mm you really need a good kamera system, really made for digital and not old 4x5 systems.
The sharpness of the Rodenstock 35 mm is not bad, SA 38 mm seems be better-a bit- the Digitar 35 mm is much sharper at App 8, 11 but at 16 they are similar- you need to use 16 at big shift. The 55 mm is sharper than 35 mm, it is much more easier to use and have not these big color cast.
sadly only 32 mm HR is a really good lens for 80 mln backs, but very expensive, and I never see it second hand.
