The Linhof 001177 Triple Recessed Lensboard is used with the M 679cs camera with any lens mounted in a "01" size Rollei electronic shutter.
Its deeply-recessed shutter flange position permits the maximum extension of the camera's standards, permitting full access to shifts/swings/tilts without the physical nature of the compressed bellows limiting your creativity.
Lenses specified to use this board include Rodenstock's 35mm Apo-Grandagon, 35mm Apo-Sironar-Digital, 35mm Digaron-S, & 23mm Digaron.
