    Of course, a real manual camera wouldn't have a viewfinder or a shutter.

  2. I think you're right about that.....I understand the spot meter position,
    and the center weighted, but the "Matrix" stuff is over my head.....I only
    use it in P mode, when I really don't want to think about what I'm doing,
    and just expect the camera to do it all for me......(like when I'm in a real

  3. Ah, but you are "proving" my point...;-)
    In "P" mode, the shutter is limited to 1/60th-1/250th regardless of
    what you adjust when using flash, which limits your ability to properly
    match the lens FL to the best shutter speed and aperture selection
    for optimum ambient-light exposures when shooting in the abysmally
    low light levels often found in churches and in reception halls. Using
    just the auto fill ratios also results in too much fill-flash - and the amount
    of fill-ratio that the camera-flash combination is using is unknown
    and undetermined by the photographer. With Nikon gear (and some
    others), you can turn off the auto fill ratio (which is -0 to -2/3rd stop,
    depending on amount of ambient light underexposure). Switching to
    A, S, or M modes permits a wider range of shutter speeds to be selected
    with flash (F100, F5) and this gives you better control over the aperture
    selected for correct low-light exposure. You can then disable the auto
    fill ratio and select your own ratio in 1/3rd stop increments. For color
    negatives, I find -1 *stop* (not one increment) flash TTL underexposure
    works well much of the time - though in very low light, I may decrease
    this to "0" for 1:1, and increase the film ASA rating 2/3rds of a stop
    (since both the ambient light and flash light are contributing full
    exposure). With all, I always set the ASA 1/3rd-2/3rd stop lower
    on the camera than the film rating for a bit more "pad" for accidental
    underexposure with white walls or if the lighting color balance is
    far from daylight (which it usually is). BTW, "fill-flash" is just
    that: it is light added to full normal ambient-light exposure to raise
    the lower tones slightly. Used well, the flash rarely distinctly shows
    in the photo - except as more "open-looking" shadow areas...

  5. Oh, can that one cause trouble unless you really know how to use
    it, and can take the time to do it properly (which is silly with 35mm
    using a good center-weighted metering pattern with some idea
    of what that means...;-)
    Ah, "snapshot" mode...;-)
    I use MM only with fast shooting with color negative materials,
    but prefer the better control offered by the M, A, and S modes
    (at least with flash...). For all else, the "roll-o'-th'-dice" aspect
    of Matrix Metering is not useful in that I can get more consistently
    good exposures using the reliable info from center-weighted metering
    without MM...

  6. Ahhhh.....I was not aware that I had any control over the auto-fill
    ratio......It's back to the manual for me....Thanks....

  7. Yes.....I don't mind automation as long as I know what the machine is
    doing.....ie: - I could do it myself if I had to. But when the machine is
    doing something that I don't understand, that's where I draw the
    line......Nikon says, or at least implies, that in MM mode, it searches
    through thousands of pictures that it has stored in it's memory, and finds
    the picture that I'm about to take, and sets its speed and aperature to
    whatever it thinks a pro would use to take that picture......In the first
    place, I find all that very hard to believe, and in the second place, even
    if it were true, I wouldn't want it to do that for me.....It reminds me of
    the story about the golfer who teed off and his caddy said, "Thats exactly
    where Mr. Snead put his drive yeaterday." So the guy asks, "You caddied for
    Sam Snead yesterday/" - Yes, the caddy says. Then, later on, faced with a
    water hazard on the 5th hole, the guy asks the caddy, "What club did Mr.
    Snead use on this hole yesterday? - The caddy says, "A six iron". So the guy
    hits a beautiful six iron shot right in the middle of the lake....."I
    thought you said that Sam Snead used a six iron on this hole yeasteday?" And
    the caddy says, "He did.....And that's where his drive went yesterday,
    too.....right in the middle of the lake."

    A lot of rambling in the replies... Certainly my SB80 and 22 set the
    flash at 1/250th... but I supect the Metz sets the flash at 1/60th..
    sort of a common standard... certainly the least common denominator..
    between brands.

    The shutter speeds won't affect the flash exposure... but may affect
    the ambient light exposure.

    If this bothers you, then take the camera and flash off auto, and set
    things manually.

    You could be right. I am using the SCA 3401 adapter, but on the web site
    of Metz I found that currently the SCA 3402 is adviced. However, I
    couldn't find a clue that this will solve this problem. Normally I use
    my Nikon in A-mode. I was taking pictures in a room with low
    environmental light (and as said before I wasn't using the flash in
    fill-in mode). Since my flash was the main source of light, I expected
    that it would automatically let the camera select a speed of 1/250 s.

    F100 will always default to 1/60 flash synch speed on P, usually on A, you
    cannot be 100% of the pre-set flash synch speed on anything but M

    The camera assumes you are using the flash in low light or dark conditions
    and wants to provide the maximum amount of ambient light to supplement the
    Gregg, Nov 20, 2003
  11. I do not think that this is true...
    The P shutter speed range is limited to 1/60-1/250, depending
    on ambient-light exposure needs; in A mode, the shutter speed
    can vary anywhere up to 1/250th; in M mode and S mode, you
    can set anything up to 1/250th when the flash is on...
    No - it adjusts the shutter speed (if possible in the mode selected,
    and with the limitations pointed out above, when the flash is switched
    on) to match the requirements for correct ambient-light exposure.
    Try the various modes with fast film used outdoors in daylight, with
    the flash switched on...;-)
