I just tried to purchase through Adorama and was very surprised to learn they were going to charge me 7% tax on $1999 (NJ resident). I suspect Adorama has a warehouse in NJ or something like that. Next I tried the Amazon link above, the lens was $2299 (yes I tried the "more buying choices" on the right), not sure if I was forced to pay tax or not. I will pay close attention in the near future, I'd be very happy to get this lens in the near future for $1699 net cost to me.
