Just came back from Tin Cheung (HK),
Wanted to get a Sigma lense.
Was told it is a grey set and have no warranty in HongKong & Australia,
but he say that i still CAN claim warranty at any Sigma Service center outside HongKong & Australia.
I saw the Sigma warranty card in the box, look similar to my other Sigma len's warranty card from Sg.
Anyone can advice if that is true ?
