I will add that one of the challenges of it is that the image through the viewfinder gets darker as you stop down the iris or add ND’s. Another thing to consider is how loud it is — so if you’re recording sound, that might not be possible with that camera.
Also, one thing I struggled a little with is that the Bolex I used had to be cranked for each take. We got about 26 seconds (24 fps) for a fully wound motor.
In the results I got back, I feel like the footage I shot on the 10mm lens generally felt a bit fuzzy (even stopped down a bit) while the footage shot on the 25mm lens came out a lot sharper and crisp. I can’t share footage/stills yet otherwise I’d post a couple here for you
