unfilled warranty =! unlimited warranty.
Don't be silly, all my L lenses too come with unfilled warranty, that doesn't mean anything at all cause once the lens is sold out from the shop, they will update the serial no and the manufacturer will activate the warranty on the day itself. No such thing as unfilled means you buy the lens, use for a decade or so and you expect the warranty still remain.

Typical mindset ma. Unfilled means all the time.

i see. so how long is my warranty then? as my seller says that i can send my lens back to him anytime.

oh wait, he din mention it will be FOC.

1 year warranty only la, your set and my set are grey set.
Within one year is free la, after that, I don't think so.
