Odd behaviour of the Canon 5D Mark II

    Hi all!

    I'm puzzled at my 5D Mark II behaviour from time to time and I'm not sure
    what causes it. I only hope it's a setting and not the camera (it does this
    from time to time since I got it in mid December). I'm not sure in what
    circumstance it does it. All I know is I can't duplicate it when I want.

    Sometimes, I aim at the subject and with button halfway pressed, I hear and
    see that focus is "ON", but if I want to re-focus (because I focussed on
    something too light or too dark), it doesn't seem to "catch", in other words
    it won't focus again. It takes forever to get it going again.

    ALSO I'm not sure if it's necessarily in conjunction with the above, but
    sometimes, I shoot a photo and instead of showing on the LCD for 4 sec. as
    set, it only shows very briefly and disappears.

    A similar phenomenon to the above also happens if I want to review the
    latest photos and erase one. I press the review button, the latest photo
    appears and disappears as fast or appears and when I press the erase button,
    it disappears...

    The only thing I've tried lately (and it hasn't done it since, but I've
    taken few pictures), I set the "C FN III - autofocus drive" at *focus
    search off*

    I've read my instruction book so often it's half torn (true). I'm waiting
    for the "Lantern series" to come out because it explains all the settings
    much better. However, it's only due at the beginning of May.

    Any idea? Thanks,

    Marcel

    Charles,
    You are right. Your assumption is right on.
    I must be somehow inadvertently pressing some control... but which one?
    Thanks,
    Marcel

    David,
    Why would the DoF button do this?
    By the way, I did try this and EXACTLY the same symptoms show: as soon as,
    and as long as I touch the DoF, the camera won't focus and if I shoot, the
    image doesn't show. If I let go the button, it shows and if I press it
    again, it disappears.
    Thanks a million! I think this must be it!
    Best regards, Marcel

    Thanks Richard!
    Surely it could be, but I'm hoping as David suggested, I might have pressed
    the Dof button unintentionally. As a matter of fact, I have to revisit the
    function of this button, the existence of which I had completely forgotton
    about.
    These days, there are so many buttons... one can presse the wrong one, not
    knowing it.
    Here's a tidbit. When I first bought my Honda Accord, sometimes I would find
    ALL the windows ½ an inch lowered when I got back to the car. I mentioned it
    to Honda, but they couldn't understand why. One day, I did the usual as I
    approached the car: I pressed the "open" key twice to unlock all doors,
    leaving my finger on the key a little longer the second time. The windows
    all opened. It's only then that I realised that pressing longer the second
    time would open all windows, a nice thing for when it's hot outside... not
    if you're not careful ;-)
