    Nikon FM2 Film Advance Question

    Is it bad to store my FM2 with the shutter cocked ready to shoot? I am guessing long term storage like that is not good, but I dont know that for sure.

    What's the real story on if this is good or bad?

    Thanks!

    I store mine cocked. Auto wind cameras store that way by default.

    Autowind cameras have electronic shutters so there is nothing 'cocked' until the power is switched on.

    The FM2 is mechanical through and through and the operation and accuracy of the shutter is dependent on a finely balanced spring tension. Leaving it cocked will upset that balance/accuracy so it is best left un-cocked.

    Good point BMbikerider

    I still intend to keep mine cocked, the bigger risk for me is not being ready for a shot. Nothing more disappointing than seeing a great shot, raising the camera, focusing, and the shot fleeting away because the camera wasn't cocked.

    Had my FM2 for 4ish years now with no appearant change in shutter time.

    Autowind camera still have the regular spring operated shutter. Electronically controlled shutter is only for the timing of the second curtain. It's still under the same stress if any. However, I read somewhere by Nikon that it's ok to leave the shutter cocked for a long time including fully mechanical shutter like the FM or FM2

    I wouldn't worry either way, its not a firearm.... but the beauty of Nikons is they can be carried in Condition One safely, just thumb the wind lever open and fire away.

    Being a toolmaker I understand intimately the nature of metals. A spring under tension after a while will lose some of its strength. I would leave a camera in storage not cocked.However leaving a camera shutter cocked for a month or 6 probably wouldn't hurt it provided its stored correctly.
    Even so, I feel that you should exercise the shutter of unused cameras once a month, this gives you the excuse to play with your cameras.Unlike firearms dry firing a camera without film/ammo won't hurt it.

    I think the F2 manual tells you to store the camera unwound

    Just checked the FM2 manual under storage. Pull batteries, avoid high temp, humidity, naphthaline, camphor. In humid areas put it in a plastic bag with some desiccant.

    Yeah, the F2 manual specifically says not to leave the shutter cocked. The F3 and FM2n manuals don't say if you should or not.

    Unfortunately, it seems to me that the only way to close this case once and for all would be to store two absolutely identical bodies with the same shutter count for ten or more years, one with the shutter cocked and the other without.

    Personally, I store my F2 with the shutter uncocked, since the manual says too. I also store my F3 with the shutter uncocked, since its shutter is similar to the F2's. My FM2n is stored with the shutter cocked since it has more in common with modern shutters such as those found in the F90 and F4, both of which have built-in motor drives.

    If you have an MD12 on the FM2, isn't the shutter going to be cocked until you remove it, or finish the roll?
