Dear All,

I have a Finepix F810. At the long end of the zoom I was getting two strange spots. The camera was replaced straight away, however I would be interested if anyone could think of what would have caused it?

The spots would fade in as the zoom went up to x4

many thanks, Alex.

PS, Cameras2u.com were brilliant and replaced it the day after I reported the fault.

I tried giving the lens a clean on the outside, but made no difference.

The spot did not change size when zooming. it just came in and out of vision.

It was probablyspecks of dust or condensation onor near the sensor (althoughthey look larger than a dust spot would usually look).

Hereareexamples of dust spots that look to be on or neara digicam'ssensor (visible at longer focal lengths withtwo differentSony DSC-W1 cameras):

Smaller Apertures (like the camera would select if you pointed it at a bright sky) also make defects more apparent.

It's definitely a faulty CCD or dust on the CCD.

My Fuji S602 has exhibited this exact problem on 2 different occasions, one during warranty when it was replaced & the other outside warranty when it cost £120 to have it repaired.

Next time it happens, I'll probably ditch the S602.

If it was a faulty ccd, the spot wouldn't be that big and would be present all the time. I think it is more likely that one of the internal lens elements has a smudge or flaw on it.

Oops, double-post. Very easy to do with this forum software.

Looks like something on the lens. Maybe a water spot?

Brad

PS Is that a UFO in the top right hand corner?

j/k

Hadn't noticed the UFO, I have now! The spots could be from another world!!

Thanks for your inputs, if it was dust etc, I hope it didnt get in while I was using it, hoepfully they are quite well sealed....
