    After reading comments in another thread about making mirrors lock up on
    Pentax screw mount bodies I tried it out on a Spotmatic F and an ES body.
    Darned if it didn't work!

    Just a very fast tap on the shutter release button causes the mirror to stay
    up, without firing the shutter. Press the shutter release once more and,
    sure enough, the shutter fires and the mirror returns to its normal down
    position.

    I have never seen this technique described anywhere--not in Asahi Pentax's
    literature, not in the book, "The Pentax Way" by Herbert Kepplar, not on any
    Pentax website that I have ever browsed!

    I did once see a modified Spotmatic, with a switch identical to the meter
    on-off/stopdown switch, mounted on the opposite side of the camera, that
    locked the meter in place. I was told that it was a factory service center
    modification, available when Honeywell operated Pentax service centers at
    about 8 locations throughout the United States. I have not seen another
    such modified camera, and all this time I just assumed that mirror lock-up
    was one feature that the Spotmatic / ES shooter would have to live without.

    Since I do a lot of work with the camera mounted on a tripod, this
    newly-found ability to lock up the mirror prior to firing the shot will add
    to my image quality, by reducing camera shake. Thanks to those that posted
    the information.

    After having been discontinued for over 25 years, one would have thought
    that there was nothing new to be learned about Pentax screw-mount cameras.
    Thanks again to those who posted this new information.

    so now let's hear from someone w/a Spotmatic II. i have an outfit,
    the camera, however, is in NM.

    yes, a quality feature and the original purpose it serves. --Loren

    A while ago I discovered that you could do this with an MX, but I didn't
    know it worked with the S series bodies as well. You live and learn, eh.

    This undocumented feature is more know for the Pentax MX.
    It's working on mines SV, ES, SpF, SP500, KX and MX, but not on the K2,
    ME/MEsuper.
    KX and K2 haven real mirror lock up feature.
