    There are definitely parts of shutters that should have no lubrication, as you say.
    i agree .. examples are always KEY .. because as you say people quote and requote and eventually things get
    askew .. i can imagine who knows when someone suggests i said "no shutters ever need any lubrication " ...

    ( i should have used examples in my earlier post )

    john
    ask me how ..

    So, I'd say the answer is: in theory, with excellent maintenance and proper lubricants, shutters shouldn't require periodic "exercise," but in reality, with the actual maintenance that many shutters that most people use have had, it doesn't hurt to get things moving once in a while.

    I have 22 working LF shutters, if I've counted properly, all in various states of maintenance and frequency of use, and periodically I'll go through them all and make sure they're running properly. I sell off things that I really know I don't need, so they don't become a burden to maintain.

    Old Ilex/Acme shutters seem to benefit the most from periodic exercise, particularly at the slow speeds.

    My Pentax 165mm leaf shutter lens is stored with the shutter released, as per instructions on storage after use. It's no big effort to think of this at the end of a day's shoot.
    I think it would be more of problem for focal plane shutters in cameras that haven't been exercised in a long while e.g. loss of accuracy over time.

    I'm really surprised no one recommended WD-40 as a cure-all.

    Well, just about every other bad idea was covered. Many think it's actually a lubricant.....

    WD-40 is paraffin. It actually does work well as a lubricant in loose-fitting mechanisms like locks and firearms.

    But its main purpose is water displacement, hence the WD name. It's used to protect metal from corrosion.

    I exercise my LF shutters a couple times right before I pull the darkslide. The main reason -- it makes sure that I have closed the lens (they won't fire if they are open).

    Now I just need to find a way to remind myself that I have the lens cap on my barrel lenses before I pull the darkslide! LOL!

    At least with LF landscape, a bad day of photography can still be a good day of exercise.
