    Are people having a lot of problems with this? Or is it pretty easy to
    adapt?

    A spot meter is a useful tool for tricky lighting conditions where there is
    a big range between the brightest and darkest portions of the image. You
    can meter on the brightest portions to be certain they won't be over-exposed
    and check the shadow to see how much under-exposed they are going to be.

    I miss having spot meter on my D60 which has the same metering system and
    the 10D. This is one of the features that puts the 10D in the class of a
    hobbyist camera rather than a more advance market. It doesn't prevent the
    camera from taking excellent pictures so don't blame the lack of a spot
    meter if you can't get top notch pictures with a 10D.

    It is relatively easy to work around this shortcoming. You can bracket your
    shot if in doubt and select the best exposure later when you can view the
    image on your computer. You can look at the image histogram on the camera
    after you have taken the shot and the over-exposed areas will flash. Change
    the exposure and shoot again.

    In many ways, learning to use the review features of the 10D is better than
    having a spot meter because you can check immediately whether you got the
    exposure right and shoot again if you didn't.

    I agree with you (I'd have to try the centre weighting), my Mamiya
    DSX1000 bought 27 years ago provides spot metering. In fact it was the
    spot and totally manual control that made me chose it.
    I am not sure this is the case with DSLR, in fact since you can obtain a
    light reading (essential for manual exposure) before the shutter opens
    then they can not do so.

  5. I don't see it as any problem at all. I never used a 1 degree spotmeter
    very much, a 9% "limited area" circle is just fine for my purposes.

    Most of the SLRs I grew up with (Nikon F, F2, FM, FE2, F3) all had a
    fixed 60/40 centerweighted meter pattern (85/15 for the F3), and it was
    never a problem either.

    I guess it depends upon what you're used to. A 9% circle seems pretty
    tight as it is.

    In message <-berlin.de>,
    No, they don't. The shutter is only open for the exposure, and the
    sensor is not read at all until the end of the exposure.

  7. You must not do a lot of event/concert work where there are spotlights
    moving randomly. In those situations, you dial in appropriate compensation,
    spot meter on the subject's face, half-press and recompose, and get perfect
    exposures every shot, regardless of which lights are on the subject or
    pointing at the camera from behind the subject.. (As long as the lighting on
    the subject doesn't change between the half press and the shot, obviously.)

    You do have a point, though: I tried the Pentax digital spot meter in a
    store the other day for the first time, and it is clearly worlds more
    accurate than any built-in spotmeter.

    Still, I much prefer using an in-camera spot meter to in-camera
    averaging/matrixing meter. The spot meter reading is a real reading of at
    least one aspect of the scene. Everything else is random guessing.

    The fat spot on the 10D/300D can be used for spot metering if either the
    subject has a large area of the same tone or you can zoom in, and you can
    look at the histogram after the fact. But not having a spot meter is a major
    irritation.

  8. Oops. Wrong. Spot meters in consumer digitals that have them tend to be 1%
    spot meters: even better than you get on the EOS 3.
    Only if you don't know how to use a spot meter and want to operate in P&S
    mode blindly using the value the meter gives without compensation.

    With a spot meter, you determine yourself how you want a particular part of
    the image exposed, and then use the difference between what you want and mid
    gray to calculate the compensation you apply to the spot meter reading. It's
    very hard to do that when you spot is too large, because it doesn't give you
    an accurate reading of the area you based your decision on.

    Not having a spot meter is fine if you know that you will never want to
    learn how to measure exposure correctly.
    Oops. Wrong. You _are_ shooting slide film. Digital, even dSLR digital, has
    only slightly more lattitude than slide film.
    Extremely accurate _when its guess as to what you are doing matches what you
    are actually doing_. But you have no way of telling. Did you want to take a
    backlit portrait or a silhouette?
    I'd rather have something that I understand than something that's trying to
    outsmart me.

    It's a bit annoying, but I find I can live with it. 'Partial' metering
    mode seems to be the next best thing.

    Yes, I've mostly found it to be an acceptable substitute.
    Yes, but the 10D's a DSLR, not a digicam. DSLRs do it the same way that
    film SLRs do it.

    I’ve never used a spot meter, but I have been in situations where it would
    be helpful. The 9% centre is nowhere near being a good substitute.

    What I use instead is the review w/info. It takes very little time to snap
    a shot, look at the histogram, adjust exposure compensation, snap another
    shot. Certainly a hand held meter and some calculations would take much
    longer and be less accurate than just snapping a shot and looking at the
    histogram.

    New technology often introduces new ways of doing things that are totally
    different to the old ways, but if you use them effectively they work very
    well.

    Word has it that on Fri, 26 Sep 2003 21:53:44 +0000 (UTC), in this
    That depends on the situation. As I said; I'm *mostly* found it to be an
    *acceptable* substitute. There are times when I *really* wish it had
    spot metering, but they're not all that common.
    <shrug> I do that too, & have done so as standard practice since I got
    my first digital with a histogram.
    The times when I really spot metering is with stage work, when you just
    don't have time to pull up the histogram. That's when I find that
    partial metering + histogram definitely can't compete with spot
    metering.
