FYI. Here are two pictures of the lens. Like I said in my original
post, I am amazed that the only symptom is a little fuzziness.

Nice close-up photos. It's certainly not the result of heating or
impact. No ablation. More like a growth.

I hope the links work. I never tried posting pictures this way
before.

It looks like the plasticizer is coming out of the lens under the
anti-reflective coating. It's a common problem with plastic tool
handles where white plastic "mold" comes out of the plastic. Here's
an example of a Vaco nut driver:

If it really is plastic "mold" or "rot", it might be something that
Panasonic would be interested in seeing. I have no idea whom to
contact.



Then there is doll's disease, as in antique dolls with PVC soft plastic
skin, that exudes acetic acid as a breakdown product as the PVC
disintegrates in the collector's cabinet.
