This is the more desirable reflex model. What you see in the viewfinder is what you get on film. This makes things a lot easier when shooting as there is no guesswork or parallax correction. You can also see when things are in focus. The camera comes with a Cosmicar 25mm C-Mount Lens that has been professionally collimated for the Bolex Reflex. The camera has a ton of features, including 6 filming speeds:12, 16, 18, 24fps, 32 and 64fps. It also has the capability for shooting 1 frame at a time. Pickup in Brooklyn.
