*update June 2014*
There is a visible film on the objective lens. Most probably fungus. My estimate was 8 months and this new data of 6 months is close.
Can be washed away with tap water and dishwashing detergent, this method is not recommended for more expensive scopes as it can cause micro-scratches on the coating.
