I just bought my Bessa R3A last month. I have enjoyed it a lot and it served me very reliably, until I had my shutter jammed on me once.
It happened one day when I fired the shutter. I heard only one "click" instead of the usual "click-chunk". The film advance lever refused to let me advance to the next frame, and the shutter release button didn't give any response when I pressed it. I rewinded the film and opened the back, and the shutter appeared to be jammed. The film advance lever still didn't work after I rewinded the film. It appeared that the rear shutter was closed but the front shutter (the geryish one right behind the lens) was jammed in the open position.
At that point, I thought I got a lemmon and the camera must be sent back for repair.
I removed the lens and inspected the shutter. When I lightly touched the jammed shutter, it slammed back to the close position and now it worked fine again. Later, I realized it was on the last exposure of a bulk-loaded roll when the shutter jammed.
I've never heard of this issue before. I don't know why it happend or if it will happen again in the future. I don't know if it is normal or if my camera is a lemmon.
Besides, I saw a small bit of dust behind the front element of the rangefinder when I frist received the camera. And now I start to see more and more dust there. I didn't store or use my camera in places that are particularly dusty. Although the dust doesn't affect normal usage and focusing, I wonder how that happen and I'm worried the rangefinder will become more and more dusty as time passes. Isn't the rangefinder supposed to be sealed from dust?
Can you help me on this? Should I send my camera back for inspection? Any insight will be appreicated.
