PDW-F350 filter unit glass problem

Post by PUCCI » July 18th, 2014, 2:43 pm

hello to all
my name is Andrea and use the cameras f350 for many years, I possess five.
lately I see the images from the cameras to change the definition and even color, until a short time ago by putting them in the preset I needed a few corrections to make them equal. jo discovered a terrible thing: 1-479-899-11 FILTER UNIT, OPTICAL is stained as if it were neckline.
are final, desperate because checking other cameras I've noticed that you begin to stain the other units.
spare parts cost a lot.
I know for sure is that optical glass, with a kind of filter, UV protected, because the ccd 1/2 inch of the camera are very sensitive.
advice and assistance
I am attaching some pictures

It could be fungus, similar to the fungus that can effect lenses and filters. How old is the camera, the F350 came out in 2006, so they could be 8 years old now. The filter performs several functions, Low-Pass anti-aliase, UV and IR cut, plus color correction. I believe it's made up of a couple of layers. If it is fungus and it's on the outside it may clean off if the coatings have not been damaged.
