...nach 10 Jahren bekomme ich von Nikon ein Neuse?

Wer kennt die Bedeutung des Aufklebers?

Reader Chris Campbell suggests it's an RoHS symbol indicating that the product contains pollutants, such as lead, exceeding allowable standards under Chinese law. He suggests the 10 means that the pollutants will not leak out for at least 10 years under normal use. 10 years is the "Environmentally Friendly Use Period," or EFUP. These labels supposedly are required by Chinese law. Interesting - do the Chinese collect these for destruction after 10 years?
Yes! This is it! Reader Tim Devine points us to the answer, effective 01 March, 2007. It's a China RoHS symbol.
Reader Gary Caple clarifies that the 10 isn't how long the scary chemicals stay inside - the 10 means how many years of useful life the product has before it's trashed. Aha - now we know the service life of this lens! I wonder if new digital cameras will have a 2 inside the backwards circle, since digital cams are good for an average of two years before the big heave-ho. Lenses ought to last longer: I still use my Nikon manual focus lenses I bought in the 1980s.
Others propose 10 means how many years it takes the poisons to leach out. I don't know, and as the sources seem to confirm, no one really knows. It's all a Communist government trying to run things.
