Need Help: Exposure Comp Keps Changing - D70 Problem or User Problem?

    I need some help and/or a reality check. I got a Nikon D70 1 year ago
    and took about 3000 pictures without any serious problems. Camera was
    set mostly on Program, since I was still getting used to it.

    A week ago I took a trip and shot another 400 or so pictures and
    realized they were all *really* dark. It took me a little poking around
    with the settings and then i discovered to my horror that Exposure Comp
    was set to -5.0 There's no chance I did that deliberately. Changing
    Exposure Comp requires holding a button down while turning a wheel, so i
    wouldn't think it would happen accidentally very often. But, I'm in the
    computer biz and I know how fumble-fingered users can be so I wrote it
    off to my clumsiness. Someone suggested I should update firmware, so I
    did. I am now at current release, I believe.

    Tonight I went out to shoot an event. After the disaster last week
    (basically, all shots were ruined) I was careful. I used the 2-button
    reset to reset all values. I checked the Exp Comp. It was at -1.0, which
    is where I wanted it. I took a few shots and checked the histograms.
    Things looked generally ok. I kept shooting and noticed that the LCD was
    indicating that the pictures were over-exposed. I checked the
    histograms. Too high. I then checked the Exp Comp and it was at +3.0.
    I'm about 99% sure I didn't cause this.

    Is anybody else reporting problems with D70 Exposure Compensation? Am I
    doing something really klutzy? Please help. I've totally botched the
    last 2 shoots, and neither is replaceable. Luckily I used Raw format, so
    I can rescue some of the shots.

    By the way, I've got a Nikon 8008S, which I've been using for 15 years
    without any problems, including Exposure Compensation problems.

    Is it me or the camera? If it's the camera, what should I do about it?

    If it works anything like an N80, this is practically a two-handed
    operation (button near trigger + front dial rotation). Not likely an
    accidental change.

    It sounds like the settings memory (usually non-volatile RAM / EEPROM to
    survive battery changes) is bad; this should be a warranty item. If out
    of warranty, it's probably soldered to an expensive board...

    You'll probably get farther with Nikon if you can identify a pattern
    that causes it to happen (so they can recreate it) - e.g., only at
    power-on, after X photos, in manual mode, etc.

    The question that I have about this camera is: does it use a seperate
    button cell as well as the main battery pack?
    I don't own a Nikon camera, but I thought of it as a possibilty that it
    might have one to maintain setting between main battery changes.

  4. Yes, it has an internal (non-accessible AFAIK) battery - it will be
    charged when you put the main battery pack in for the first time.
