I am selling my Phase One IQ180. This is a fantastic back and it produces amazing images. It is in excellent condition and it has just been re-certified by Phase One. As you can see from the image, it has the latest firmware as well as only 4,791 actuations. The back comes with the Phase One Pelican case, 4 batteries, charger, cables and a copy of Capture One. Its only blemish are some rub marks on the glass.
Price is $29,950.00.
I might add that my Ebay id is Pogo3 and you can verify that I have sold a fair amount of my camera gear with a very good reputation.
Sorry, Mamiya mount.
Also, if one wants, I can sell the Phase One 645DF and 80mm Phase One lens for $3,795.00
