Does anyone have any experience with this lens? Either on the bolex or otherwise? I believe it is C-mount, and I was hoping to maybe pick one up to test out on a pocket cam. Just wondering if anyone has any positive or negative experiences adapting it to a M43 mount.

If it turns out to be an option keep in mind there are both C-mount and Bolex Bayonet mounts...

 

If you're going to buy one make sure you check  ;)

They came in both C-mount and Bolex bayonet mount. I haven't tried an M43 adapter on them, but I doubt a C-mount to M43 one would fit, the lens throat is too large. I'm not sure a Bolex bayonet to M43 adapter would work either (or if they even exist). 

 

Besides that, they were designed for reflex Bolexes, (which may or may not be an issue at wide apertures), and they have a 2 blade diamond-shaped aperture, which is not everyone's cup of tea in terms of the out-of-focus character.

Ah good to know. Maybe that's why I can't find any test footage online. Also thanks for letting me know about the diamond shaped bokeh.
