Nice Carsten, do you still have the Sinar?
No, I ended up selling it. It had some sort of trouble communicating with my Contax 645, and would randomly under-expose and sometimes lock up (the latter is fairly normal for medium format digital systems like this; I also had it happen with a box stock H4D-40, and have heard of it happening with other combinations too). I am not sure if it was my camera, the adapter, or the back itself. I think that for the Contax, the best back is the Phase One, probably the P45+ or something like that, but that is a step up in price. The Sinar works better on a Rolleiflex.
I loved the results though. I would love to try again sometime, but to be honest, at the time it was a relief to go back to my Leica M8 and then Nikon D3.
