I am fortunate that the shutter in my Favorit is working great. I keep running film through it to keep it that way.
Actually, the minute I finish a roll I load another and take a photo. That way the camera does not sit with the shutter tensioned.
However, to be honest, one should continually work any camera with these shutters since sitting to long between uses is not good for them, whether or not the shutter is tensioned. I try to keep my Rollei Automat and my ZI Favorit in use regularly.
Besides, the results truly are stunning!
You gotta love a fast lens;
It is almost as good as a fast horse!
