It would make sense that if a 10mm C-mount Switar covers Super-16 on an ACL, it would do so on a Bolex --- assuming that the lens mount is perfectly centered. Check the page at http://members.aol.com/Super16ACL dealing with Regular-16 lenses that cover Super-16 ... it explains that in order to judge if a lens covers Super-16 it is necessary to actually check coverage at the film plane (there is a special Bolex gizmo to do this), since through the viewfinder it could show corner vignetting that is not really there owing to the fact that because the mirror is set back from the film plane, the mirror sees a slightly different circle of coverage .
