The design flaw made by Hasselblad (or to be fair, probably their Japanese partners in the XPan project) cost me a lot of annoying and unnecessary efforts and lead me eventually to abandon the camera system.
However, if 8 secs exposures were sufficient, good results could be achieved. In this case, the main challenge was keeping up the stamina to wait for a car on this desolate and very lightly trafficked winter road ... The intervals could be 20 to 30 minutes and I had only a single chance per passing car for the composition I had envisioned.
