The funny thing is, I suspect they had an order for the lens, and then the customer couldn't pay. Or, they may have a buyer who gets a big discount for letting them use it for the show. I suspect that a lens of that size is only made on special order. It's not like you're going to stroll into Ritz camera and pick one up on a whim.
