I recall a thread a while back discussing the merits of having a cine forum. I guess that never happened. Well I have been shooting B&W 8mm for about 8 years now. Here is one of my Bolex Reflex cameras. Again, this is 8mm, so with a 100ft roll I get as much running time as the 16mm camera with the big 400ft magazine on top.

I'm using ISO 100 reversal B&W. I was just shooting with the camera today. I have two other Bolexes also. One has the EE zoom and the other has a f0.9 Switar lens on it.
