Looks like a classic case of fungus to me. Not sure if the lens is salvageable or not.

Looks like fungus to me too. I guess Malta can get pretty humid? How do you store your camera equipment?

Yes it does get humid here. I store my lenses in a case that's filled with silica gel packets.

This did not form while I was here though - it happened either on the plane trip back, or maximum within a week of having flown back (I was checking my lenses even more frequently when there). But they were there that same evening I got home. Since then the crystal shapes have not changed in shape, size, amount or area of the lens affected.

Logic would tell me if it were fungus, it would have formed slowly over time, and since last August when I first noticed them they would have gotten much worse...
