I live in France and buy from Amazon .de sometimes.
Their lenses are realy well packed, like all their other stuff.
Be sure though that it says "sold and shipped by Amazon", this way you have the full Amazon protection. Because there are offers that are only shipped by Amazon for other vendors and then things are a bit different.
If you buy from Amazon themselves, you can return whitin 30 days the article if not satisfied.
I find there is no risk at buying directly from Amazon.
Happy shoppin' happy shootin', ciao, Han
