Nikon D40/80/90 MM Exposure Problems

    Just had a chat with Nikon UK. They say Nikon are not getting any feedback
    on these problems. Also say there is a new system in operation when you
    contact tech support by phone rather than by internet. They now have to log
    every call. They suggest that anyone with this problem phone them (including
    Nikon in other countires) so they can get enough feedback for them to
    update the firmware. What they may do is to add an extra option to the menu
    which allows you to set the type of exposure control: standard or expose for
    the highlights.

    As Ken Rockwell has mentioned this problem on his site, Nikon UK suggest
    that they may actually be deliberately ignoring this problem as they tend to
    take everything he says with a very large pinch of salt. Shame, because
    there is a lot of useful stuff on his site.

    Note: if you search for Nikon it will give alternative
    cheap or free numbers rather than the premium lines. So get phoning.

    except it's mixed in with all sorts of bogus info and no real way to
    tell the difference.

    What problems? I haven't noticed any exposure problems with my D40.
    That's what exposure compensation is for.

    This a change of subject, but I'm looking for some answers about my
    Nikon D40. I generally shoot in the program mode or aperture mode.
    For outdoor photography I set my ISO at 200. (Not Automatic; I
    specifically set it to 200)

    I generally don't look at my EXIF data unless I have taken some shots
    of the same scene at different settings and want to see later which
    setting I used on the better shot.

    I've been noticing that the ISO is usually at 200 - as the camera was
    set - but will be higher or lower on some shots. On the last batch of
    photos on aperture priority I very carefully noted that the ISO was
    set to 200 both at the beginning of the session and at the end. It
    was never changed. EXIF says the ISO was usually at 200, but jumped
    up to as high as 720 on some shots.

    If I don't use the Automatic ISO setting, or shoot in Auto, what would
    override the 200 setting?

    If it makes a difference, I shoot RAW, and convert from NEF to DNG
    when I download in Bridge and I edit in CS4.

    Why are you changing the subject? Why not post a separate question? It is
    considered very bad manners to do this.

    Well, your do have to use some judgement and common sense.
    But you have failed to get the point. This is why Nikon hate this site and
    take no notice even when he has a valid point.

    You haven't got one of these cameras have you? If you had you would know
    exactly why exposure it is such a pain using EC on these cameras.

    Simple: you have to do it constantly. Compare this to other cameras in
    Nikon's range: D300 and up. Exposure is spot on nearly every time and you
    only have to make the occassional adjustment. Try one and see.

    why bother with a site that has a lot of bogus crap mixed in and where
    the author admits he deliberately makes stuff up?
    no doubt they hate it cuz he's full of shit much of the time.

    No doubt they've never heard of it and couldn't care less about it. This
    discussion reminds me of the flea with a hard-on lying on his back floating
    down the river on a cork and shouting "OPEN THE DRAW BRIDGE".

    As I said, I have a D40. I still don't know what exposure problem
    you're referring to. Could you describe the problems you've had?
    Maybe you just got a bad sample.

    Using exposure compensation is pretty easy. I haven't seen any need
    to fiddle with it.

    there have been accidents where a driver plowed into a crowd of people
    or a storefront, sometimes injuring several people. they usually claim
    the brakes didn't work or the car 'suddenly accelerated,' but it often
    turns out they had pressed the accelerator pedal by mistake. so yes,
    it does happen.
    that's just stupid.
    either your camera is grossly miscalibrated or you are doing something
    wrong. there are an awful lot of d90 users who don't seem to have this

    Sure thing, my fine ferschlugginer Focii. The mechanic and the
    waiter know you quite well by now. The waiter appreciates your
    varied orders, but the mechanic thinks otherwise, cringing every
    time that you wheel into the garage in a new make/model. Couldn't
    you pick one and stick with it, such as with the fabled 2CV?

    if the pads were against the discs all the time, then the mechanic did
    a shitty job. user error, but this time the user was the mechanic, not
    the driver.
    wow, 34. how many d40-90s has nikon sold? millions?

    I haven't used a D90, but I've used a D300, D200, D80, D70, Canon 5d,
    and over the past week or so a Canon 5dII.

    For preservation from blown highlights in scenes as you describe, then
    IMO the D80 and Canon 5d (I and II) are about the same. Nikon dslrs
    with the 1004 (IIRC) sensor ttl module seem to have better a Matrix
    metering system than Canon or Nikon's 420 sensor system. I don't know
    about metering in Canon's 1d/s range - haven't tried. But I don't read
    a lot of complaints in forums from 5d I/II users, and as you've been
    told before, on all these dslrs you've got histograms and flashing blown
    highlight previews that should allow any half competent photographer to
    nail exposures. If those features weren't needed or useful, then they
    wouldn't be there.

    P&S cameras can meter from sensor data - not TTL sensors separate from
    the imaging sensor as is the case with DSLRs (excl LV mode). So in that
    case it's relatively easy to read sensor data before taking the shot,
    and to adjust exposure accordingly.

    Even if you're right (which I admit is possible) that the d90 matrix
    system needs "tweaking" via a firmware fix, I'm still pretty sure that
    the basis of your problem is that you've gone from a D300 to a D90.
    Nikon put a cheaper 420 pixel sensor TTL metering system in the D50, and
    AFAIK have retained that cheaper system in all consumer dslrs ever since
    - IIRC the D70s was the last consumer dslr they made with the full 1005
    pixel sensor. If it didn't make a difference, then they wouldn't have
    retained the 1005 pixel sensor in their higher end models.
