Hi all,

I have had a D200 for about eight months, and while I generally love it,
it
has been plagued with a disturbing number of problems.

First was the long banding--I believe they replaced the sensor to fix
that,
but afterward pixels started dying. First I had three dead pixels
remapped,
then two months later I found about 20 new ones, which were remapped.
Now, a
month later I am finding more. Has anyone else experienced anything like
this?

But the latest and greatest weirdness became apparent recently when I
tried
to do a longish exposure--about 3 minutes--of the African night sky. I
was
shocked to find that all four corners and the top of the frame were
luminous
pink--looking like light-struck film. And the whole frame was studded
with
scores of dead-looking pixels of different sizes in white, red and blue.
But
they weren't dead; at shorter exposure times they behaved normally, with
more and more being "blown out" and luminescing as the exposure
lengthened.
There were a few at 30 secs., more at one minute, and a whole lot more at
3
mins. I didn't have the courage to test further...Likewise the pink
fringing
started at about 1 minute and grew progressively worse at longer exposure
times.

Obviously this is going back to Nikon, but I am wondering how many D200
exemplars might suffer from this kind of defect, which is not obvious in
most shooting situations. If you have a D200 and the time and inclination
please try this: Go in a dark room, put a body cap on to stop any light
from
entering at the front, and perhaps the cap on the eyepiece as well, and
do a
3 minute exposure at ISO 1600. I would be interested in hearing about the
results.

TIA,

Toby

Sony putting as much effort into their sensors as their batteries?

Same happened to your D200 too, you have such bad luck Rich?
