It doesn't sound like it. From Zeiss Warranty.
"Only products imported by Carl Zeiss Optical, Inc. and purchased in the
United States or Canada from authorized Carl Zeiss Optical, Inc.
dealers carry this Limited Lifetime Transferable Warranty. Carl Zeiss
Optical, Inc. will not provide warranty service for products purchased
through unauthorized dealers."
I wouldn't worry too much about being without a warranty on an FL though if you get a good price. They didn't have too many problems like the newer Zeiss and optically they are very close and probably a better bargain. Here's a nice one from the UK on Ebay for $1357.31 from Ace Optics which is a good dealer. They have 100% feedback.
