Bronica RF645 shutter... Hi there! I just bought a Bronica RF645 camera and loving it!! I’m a bit new to medium format film, actually a bit new to film as a whole, as I sold my CanonEOS350D in order to buy the Bronica. As I said, I just love this camera, but there is just one thing I want to know, the shutter seems to have a bit of a lag with a strange shutter sound? This is a bit of a dumb question, but do I need to keep the camera still till after the shutter sound has finished? Or is it just the mechanics inside re-arranging themselves for the next shot? I hope I make sense...

Hi Ellie, I never owned one but I think no one can answer your question for sure. However, you can perform a little test and get the answer yourself. Prepare a white target like a white wall or a white piece of constriction paper by illuminating it brightly. Open the camera (without film), keep it open. Point the camera at the target while peering through the film gate. Snap the shutter as you examine the lens from the rear. You will see a flash of light at the higher shutter speeds. What you are seeing is the working diameter of the lens uniformly illuminated (exit pupil). After a few snaps at various shutter speeds you will soon see for your self how the shutter’s open duration correlates with the sound of the shutter. Keep in mind that the shutter is mechanical; its design is closely related to a pocket watch. Lots of luck, Alan Marcus

Ellie, There should be no further noises once the shutter closes. And since this is a rangefinder camera (built by Tamron, who bought out Bronica several years ago), there is no internal mirror that flops up and down as there was in your Canon DSLR, so the entire shutter process should be extremely quiet. You should only hear two faint sounds at slower speeds - the first shutter curtain traveling across the film plane, and the second curtain following (which closes the shutter). At faster shutter speeds, these two curtains travel so close together that you should hear only one distinct sound. It may well be that you are hearing some reverberation when the second curtain comes to an abrubt halt, but this really shouldn't be. If you're hearing anything else, you may have some problems that may need professional servicing. Michael H. Cothran

Hi Ellie, If your camera goes "click...sqweee" it's OK. It's the sound of the electronic leaf shutter reseting! This camera doesn't have a focal plane shutter. Each lens has it's own electronic leaf shutter, so you won't hear or feel any "thunk" or "clunk", just hear a tiny click and then a "sqwee!" :-) Here's an audio recording of it: http://www.shutterflower.com/20060323%20012346.wav Once the camera has gone "click" you can move again! :-) Hope you have fun using your MF Rangefinder! Jon

If I may offer still another ressaurance here... I own and like this camera. The wheeze after the shutter fires is the shutter recocking itself. It is a little disconcerting at first until you figure that by the time you hear the little whir, the shutter has done its job. The vibration-free shutter is one of this camera's best features. I'd estimate that you can go a stop or even two slower with this shutter. I often use a monopod, though, when shooting 100 film.
