    Lens Controls

    Sorry, I looked everywhere but couldn't find an answer to this simple question.

    On both my lenses, there is a swtich that allows me to choose between "X", "M", "V".

    What the heck is this for? I can't figure it out? Does it have anything to do with flash usage? If so, how does that work.

    Again, I apologize for silly question, I'm sure.

    "X" is for girlie shots - check with Frank P. for more information.
    "M" is for movies - not applicable if you're shooting LF. Ignore this one.
    "V" is for vertical - especially if you're rappelling down a cliff - very important!

    Glad to help...

    Not really - they're flash sync controls:

    "When using electronic (Xenon bulbs - hence the 'X') flash, the shutter trips open as normal since the electronic flash is very quick.

    "When using 'manual flash' - M - with those traditional blue, metal wool-filled bulbs, the shutter must delay opening until the flash output of the bulb reaches maximum brightness (something in the order of 5-20milliseconds = 1/200th to 1/50th sec delay)."

    Anyone up on the "V" setting?

    Thanx Robert. I had a feeling you might be kidding.



    Ok, so that 's what I thought but, now a few follow up questions:

    1. So, leave it on X when shooting under normal natural lighting conditions?
    2. If I do decide to shoot with some modern "Xenon" flashes, what is the sync nechanism since there isn't a sync terminal on the lens. Or, is there? There is a very, very small cylinder on the lens that I can't figure out what it is. Could this be where I connect a normal PC Sync cable??
    3. OK, so, if I leave it on X for normal natural light situations AND if I"m using a flash, what is the lens doing differently??
    4. I wonder what V is for?

    V should be the selftimer, but I forgot what the exact word is that starts with V, it was german, that I remember...
    The small cylinder is indeed where you'd attach a PC sync cable.

    OK, I did find out that V is for self timer.

    But still wondering about questions 1 & 2 I have.

    thanx much

    Math answered your question 2.

    As for question 1, it really doesn't matter. I leave my shutters set to X whenever possible becuase there are fewer parts moving htat way. But if hte shutter is in good operating condition it really doesn' matter.

    K, I think it's sinking in... (a little thick here, sorry)

    X = Xenon Flash OR Normal
    M = "Old Style" Flash ONLY
    V = Self Timer

    Thanx everyone.
