Alexander Boyd Posted September 26, 2019 Share Posted September 26, 2019 Hi everyone, beginner question: I recently got a Bolex SBM. Can I change lenses while the film is loaded already? Or would I expose the film? thanks, Alex Link to comment Share on other sites More sharing options...
Premium Member Simon Wyss Posted September 26, 2019 Premium Member Share Posted September 26, 2019 No worry. The camera has a shutter between lens port and film. It may occur that the camera stops shutter open when you let the spring drive run fully down, more so at greater speeds. You just tighten the spring, the mechanism comes back to release halt, shutter is closed. Link to comment Share on other sites More sharing options...
Mark Dunn Posted September 26, 2019 Share Posted September 26, 2019 Even if the shutter doesn't close, you only lose a frame or two. The rest of the film is behind the gate so it's safe. Link to comment Share on other sites More sharing options...
