Жизнь внутри линзы Sony SAL1650 (Life inside Sony SAL1650 lense)

DT 16-50mm F2.8 SSM (SAL1650)

...и "растительность" под фронтовым стеклом линзы.

...and "vegetation" UNDER front glass of lense.

Есть ли у кого какие-либо предположения - чтобы это такое было?

Does anybody know - what it can be?

Doesn't look pretty!

How old is the lens?

Have you asked Sony for advice?

[NicoEC]

I purchased it 2012.

The only respond I have is from SonySupportUSA twitter:

We recommend that you send your unit to a Sony facility to have it checked, please visit https://goo.gl/Ag38u  -Jen

And I did not get any other answers to my requests.

This lense in "dry box" now, what I made specially for this case. Hope that reducing of humidity will solve this problem.

Is this "biological" substance or just water - I still do not know.
