Mounts large-format lenses fitted with a Copal No. 0 shutter using a recessed mounting position.
Construction and specifications
Precision-machined aluminium alloy. Lens mounting-plane rearward offset: 18.5 mm; recess internal diameter: 80.5 mm. The latter is the recess clearance diameter, not the shutter mounting hole. Check shutter dimensions, control levers and rear-element clearance.
Recessed mounting
The recess moves the lens mounting plane towards the camera, creating room for wide-angle lenses with shorter focal lengths or shorter flange focal distances. At the same lens-to-image-plane distance, it can leave more extension and movement room for the bellows. Actual infinity focus and movements remain combination-dependent; the board does not change the lens focal length or optical flange focal distance.
System configuration
Select the rear adapter and Type 1, 2 or 3 bellows for the camera or back; all three share the front board interface. SWEBO lens boards fit all SWEBO mini view camera models.
Configuration notes
Lens-side accessory only; illustrated lenses, shutters, camera platforms, bellows and cameras/backs are not included. Check retention, aperture/shutter operation, clearance, image circle and focusing range for the assembly. Movements come from the platform; mechanical mounting does not imply electronic control.
