Nikon Coolpix 2500 (Spots on images)

Anyone else heard of this problem?

Having recently taken a lot of images with the Coolpix 2500 and
finding that 80% of the ones taken using flash have what appears to be
translucent bubbles and solid white spots all over them the camera was
sent to Nikon for inspection. I would point out that the lens was kept
clean at all times and the position and intensity of the spots varied
from shot to shot

They have now replied saying that digital flash photography ALWAYS
produces this result if there is any dust whatsoever in the
atmosphere. Whilst the 3 dealers say it is a faulty light reader chip
in the camera itself.

As in the series of photos, two shots taken 10 seconds apart produced
totally differing results, one perfect one with spots and Nikon
refused to offer any explanation as to why, I would, before I hit
Nikon again, be interested to hear if anyone has had the same sort of
problem.

I have the same problem.

The Nikon people are correct. Having one perfect one with spots (and, I
presume, another one perfect one without spots) is just a matter of
luck. Being in a place where there is dust and using on-camera flash
guarantees blobs in the photos. Either stop using flash, or get the flash
off the camera a foot or more so that it doesn't reflect light back into
the lens. Same as driving in the fog with high beams on.

A clean lens will not clean the room. Call you mom, she can remove
them. They are dust in the air.

It is dust, and the flash too close to the sensor. Try other
lightning away from camera, and it will not appear.

I haven't seen it yet on my Canon EOS 300D, so meybe it is time to
pay $999 for an upgrade ? :)

Yes, you do tend to see this effect. It is exacerbated by:

- the built-in flash is close to the lens, with little axial separation.

- the depth of field is huge, so things that would be out of focus on a
35mm camera tend to be in focus on a digital camera.

So try an off-camera flash or reducing the dust in the environment!!!

Cheers,
David
