I am selling a mint a Kapture Group Fuji GX680 Phase One Digital Back Adapter kit.
It is for Mamiya/Phase mount Phase One backs.
It lets you use all shutter speeds and B on the Fuji GX680 all versions.
Works with P series and IQ series backs.
It controls both camera and back.
The back adapter supports rotation on the Fuji so you can shoot vertical or horizontal without removing the Digital Back.
It also comes with a 6 foot remote shutter release.
Price $650 (New the kit is $850 with the current sale.)
PM me if you are interested
