Hope this is ok to list.
I have seen a few posts of those looking for mf solutions and also digital back for low price.
This listing shows Contax 645 & extras with the 120 macro lens (This is one of my favorite lenses) and the Kodak DCS Proback
Last checked it was at around $2,000
The back is reported to have over 40,000 acuations.
Looks like a great entry price to mf digital imaging(of course the price probably will go up towards the end of the auction)??
I have no connection to this listing (ends on Jan 14th)
