Racer, I do not think it can focus to infinity!
For any lens/camera combination, it should fulfill 2 requirements at least:
1. The lens should be brought at its correct flange focal distance from the film. Minor error toward (-)less, could be adjusted for with focussing or any mechanical interface, but any error toward (+)longer, is not.
2. Image circle of lens should cover the intended film format used.
The flange focal length of pentacon above(SLR), I think is roughly near to the flange focal length of pentax 67 lenses which is roughly 85mm.
The flange focal length of hasselblad V lenses is 75mm roughly.
Most 6X6 lenses can cover 6X7 film with minor or some vignette.
