Thats daylight film, so take that into consideration. You won't want to shoot at f16 anyway (too much diffraction) so I'd put a ND filter on there. I usually use a 3-stop filter with ISO 100 film when shooting outdoors. (thats .3 x3 = 0.9ND). You can tape a filter on there. Using a hand-held meter and the indicated aperture number should be fine.
If you get serious about it you can have SK Grimes make an adapter. I had them make a few for my Bolex and they were about $60 each.
I used to have a bunch of small series IV and V adapters for movie cameras but sold them all on e-bay as they did not fit Bolex. You can get the small Series IV and V filters here:
