Some users may notice the symbol shown below, printed on the bottom of their lens or camera

This symbol indicates that the lens meets Chinese regulations regarding the use of environmentally friendly material used in the construction of the lens or camera. In China all items that meet these legations must display the above symbol. Any items that do not meet the Restriction of Hazardous Substances (RoHS) regulations can no longer be imported into Europe so no similar logo is required for Europe .
