Can anyone help with this? I recently purchases a body trhat came with a number of back adapters. it was presumed by both the seller and me (without seeing them in person) that they adapter the back of the camera. However, on receiving them, it seems they are actually adapters for a digital back. The Contax 645 adapter in mix fits neatly on the C645.
I would guess that they might be for a Sinar or Jenoptik back, but I just don't know which one. I further guess that since they were all together they fit the same back. A picture of them, along with the boxes they came in, are pictured below.
The adapters that I have are the following:
1) AP Contax 645 AF (Adapterplatte Contax 645 017953-079-24)
2) AP Hasselblad EL (Adapterplatte Hasselbald EL 017953-050-24 -- but the adapter itself says "Hasselblad CW")
3) AP Mamiya 645 AF/AFD
4) Mamiya RZ
Any ideas about this?
