i finally got the adapter for my Hartblei super rotator tilt shift lens , the lens was a bit of a bargain as it was advertised as a Contax 645 mount (difficult to find adapters to Canon ef mount) but was actually a Pentacon 6 mount (easy to get an adapter for )
so far i have only managed to try it out in the dark and extreme cold ,i really need to get out in daylight to get the hang the focus
