I'm not sure if your post was meant to reassure or not, but in fact,
I'm sincerely concerned. $900. is (for me) an awful lot of money; and
to be unsure whether this instrument was "marked down" because of these
fluctuations is extremely unsettling. Thank you for taking the time to
reply, in any event.

What kind of lights do you have at the room where you get this? Maybe
it's fluorescent lights confusing the meter (although I have never seen
this myself).

IIRC, NOBODY got the fact that your last camera was malfunctioning as
you finally described; peobably because you never described it that
way.
I know I asked for verification twice, and didn't get it.
So, let's start from scratch: describe exactly what problem you're
having.
Not generally, but exactly; ar eyou using a tripod? Indoors (if so,
what lighting conditions), outdoors, underwater, what? What is the
subject? What is the camera set to? What lens/filters are you using?
Have you read/do you understand the manual?
The BUSY signal can be very normal if the auto-focus can't find
anything to focus on.
In general, you need to help us help you.

Dealing with Canon tech support is not easy. They are nice enough but
here is what they are going to tell you.
There are no known problems so you should send it to a repair center. I
guarantee you they will not be able to duplicate your problem and you
will get the camera back two weeks later with the same problem, assuming
there is in fact a problem.

I had a chance to play with an 400D at National Camera Exchange downtown
Minneapolis, and the store is not very brightly lit. No exposure problems
that I could see. Especially if you move off of matrix metering, or whatever
it is called on Canons.

I don't mean to be rude, but since there are "flucuations" on muliple cameras,
I really think it likely it is the photographer [or his method] may be to
blame for the flucuations.

I don't have a DR. But I do have fluctuations in some of my work:

That would be my guess. Low light means low contrast and the focus sensor
has trouble with that.

Regarding your problem, you did not say whether it occurs in areas lit
with fluorescent lights or not. Since it has happened twice to you, I am
guessing it is something in the environment in which you use the camera
that causes this (or in your way of using it, but I can't think of
anything).

The point about fluorescent lights is that they (sort of) switch on and
off very quickly, so the colour and intensity of light emitted by them
actually changes very quickly with time (too fast for us to see). It is
not inconceivable that the metering sensor in your camera just happens
to have the "right" reaction time to be confused by this. I have never
actually had or heard of such a problem, though. I have noticed auto
white balance getting fooled by fluorescent lights (and being
incosistent between different shots).

Anyway. Chances that two cameras in a row are faulty are quite low, I'd
say. Something else is going on here.

Go easy Bill, you're setting a dangerous precedent. You really want
posters to describe their problem with all the relevant detail. That
takes all the fun out of guessing.

I don't mean to scare you but if you are having a problem and they can't
re-create easily you may be into sending it back several times. I would
make sure you don't have something set wrong or maybe you can find
someone that has the same camera and see if he can see what you are
talking about.
When you say fluctuating exposure what do you mean? Do you get a
different exposure taking a second picture of the same thing, one right
after the other?

When the posters catch on and learn to slip in red herrings . . .

THE FUN WILL RETURN!


More seriously, Bill asked good questions. Whether the answers
help provide a solution or not, they can greatly reduce the time
needed to find an answer or realize that none are to be had. That
can amount to a savings of several days or more . . .
