Found this on the rear element of a lens about 1 month old.



can anyone advise whether this is a fungus that is starting to grow? or, what else could it be?

Thank you.

once i noticed the "stain" on the lens, so I cleaned it with some lens cleaning solution and make sure that the stain is removed before i put on the lens cover and keep it. But after fews week when i took out the lens and inspect, there are some new stains.. how did the stain get in..?

And strangely, there isn't any similiar stains on the front element. only on the rear element.

you mean never?
