Is this Fungus?

Well sunshine's something you have no shortage of over there so fingers crossed!

Sunshine eh? Well we are blessed with plenty of that in our part of the world, unlike our UK based brethren
Actually, me and the missus have just climbed out of the pool. 26 degrees in, and 28 degrees out

ha,ha,ha,ha, in a Vincent Price kinda way.

I recently bought a Pentax A 24mm 2.8 wide angle from a car boot sale for £10,which has a fungal infection of both front/rear elements and the results are excellent.It is now my favourite lens.I too was worried re qaurantine etc ,but after much research decided not to bother as I keep all my gear out of damp conditions etc.Just enjoy using it sounds like you got a bargain
