These aluminium-alloy lens boards mount large-format lenses with matching shutter installation dimensions on SWEBO mini view cameras. Select the board by the actual shutter mounting specification, including the retaining ring, rather than by focal length or shutter brand alone.
Mounting dimensions
| S2051 — Copal 0 | 34.6 mm board mounting-hole diameter |
| S2052 — Copal 1 | 41.6 mm board mounting-hole diameter |
| S2238 — Compur 00 | 26.7 mm board mounting-hole diameter |
These dimensions describe the lens-board openings, not the shutters’ clear apertures.
System configuration
SWEBO lens boards fit all SWEBO mini view camera models. Type 1, Type 2 and Type 3 bellows share the front lens-board interface; select the rear adapter and bellows type for the intended camera or back.
Configuration notes
The lens boards are lens-side accessories. Illustrated lenses, shutters, camera platforms, bellows and cameras or backs are separate components. Check retention, aperture and shutter operation, mechanical clearance, lens image circle and focusing range for the assembly. Camera movements come from the platform; mechanical mounting does not provide electronic control.
