I wouldn't worry too much about the warranty because Nikon provides a generous 5 warranty on its equipments. I am more concern about Amazon's return policy though. It's only 30 days. I received my 28-300mm lens almost 2 weeks now and haven't gotten the body to try it out. If the body comes after the 30 days period and I find that the lens is defective or not to my liking, what am I going to do with the lens? Amazon.com should give us an option whether we want to receive the lens or not when the body is not available for shipment.
