    Hi all,

    I shooted many rolls with my Mamiya 645 and few weeks ago it decided to block in the middle of a roll.
    The mirror was in "UP" position and impossible to unlock anything.
    In the end I managed to remove the 120 back, rewind the film by hand and unlock the camera I don't know how... but as I never had this problem, I'm wondering if you know what can cause this.

    cheers

    I had this happen few times with M645Super. It seems (for me), replacing the battery cured the problem. Even when the "battery check" light comes on brightly, I was experiencing this issue.

    Has the battery gone flat ? That's what happens, the shutter fires and then then stays open like that.

    Huh, I tried to change the battery too but it was still blocked :/
    I could hear a small "click" when I trying to shoot but nothing more.

    In the end, I loaded a "fake" film, it unlocked the box and I could "shoot" and rewind correctly... strange :/

    I shooted few films since that problem and it looks okay now...
    If it happens again, I will change the battery and unlock it the same way :smile:
