Hi everybody ! I am completely new to the analog mamiya world and received my RZ67 set yesterday. I just wanted to try a bit the beast without film and came across the following problem : when I try to "take" a shot, I am only able to use the shutter once. Then, whatever I try, I must remove the lens before being able to "take" an other shot. Here are my step-by-step actions: - Without the lens, with the RM lever on "white", I push the cocking lever to set the mirror. - I then attach the lens. - I then take a picture, everything works fine. I even checked without the Film Holder and the mirror/shutter are working properly. But then, I can not just use the cocking lever and take several other frames. The shutter refuse to work and the monitor light for "Cocking Lever Not Set" illuminate. To take an other shot, I must restart from scratch by removing the lens,... Anyone has an idea ? That would be really helpful ! Thanks a lot in advance !
