Specks on images and LCD


[link to this post]
 
I have a Panasonic FX35 10 megapix 4x optical zoom. If the camera is used on wide-angle, all is well but as soon as you zoom in, two black specks appear on both the display and any images, always in the same place. The lens is clean so what may be causing this and why should zooming aggravate the problem?

Dead pixel on the CCD?

Interpolaton may mask this on the wide angle shots.

Thanks Andrew, sounds like an expensive repair? I would have thought dead pixels would be more clearly defined but these look as if something has crawled in and died, in fact one looks like a bit of fluff!!

That's dust. Try using the sensor-cleaning function.

This camera is a little pocket job, not a DSLR!

No such refinement unfortunately!

Does look more dusty than a pixel

Andrew, thanks so much, you have been busy!! Excellent video too, I was wondering what to do this weekend grin

Not sure I would use a cotton bud to clean the sensor/filter though, perhaps my expensive anti-static lens brush.

Anyway, a very Happy Christmas to you and all!

Well I had a go and took it apart with my jeweller's screwdriver and a pair of tweezers from a Christmas cracker wink The dust specks were clearly visible to the naked eye, both sides of the filter. Cleaned it all up with my Arctic Butterfly. The most difficult part was refitting the filter in its rubber mount but I did not have to disconnect any ribbon cables.

However, testing the camera afterwards reveals I have introduced some very fine dust but now I know what I'm doing, will have another go grin

You'll have to build yourself a clean room for your next project!
