AFAIK the definitive analysis is here:
To skip all the detailed discussion of optics and summarize: it's about aperture, not focal length.
> STANDARD C-MOUNT LENSES WILL WORK WELL THROUGH THE BOLEX PRISM PROVIDED THAT THEY ARE STOPPED-DOWN PAST ABOUT F/3.2
> This rule contradicts the rule given in the Bolex literature that for focal lengths less than 50mm and only for these, H16 RX cameras require RX-mount lenses. In fact a very fast 100mm C-mount lens will give poor results wide-open on the Bolex H16 RX, whereas a 10mm C-mount lens will give fine results stopped-down on the Bolex H16 RX. There is no truth in the old prescription.
