B&H has the legendary Canon EF 1200mm f/5.6L USM lens in stock. A single used unit in excellent condition is currently priced at $180,000. Check it out here at B&H Photo.
Update: A little back story….
They had one in 2010 available for $120,000, which you see pictured in the top image.
And then, back in 2008, they had on for $99,000.
From Canon:
This remarkable lens is the longest in the world with full autofocus capability. Two fluorite elements for superb image quality, make it ideal for many professional applications where it’s impossible to get close to the subject. Fully compatible with any EOS SLR, including digital bodies, autofocus performance is silent and instantaneous thanks to the Ultrasonic Motor. It’s also compatible with the Canon Extender EF 1.4x II (making it a 1700mm f/8) and EF 2x II (2400mm f/11). Available upon special order.
That’s interesting. Evidently, they’ve had this lens for sale for several years, and no one has stepped up to purchase it. At one time it was selling for about $70K. I guess inflation IS a real thing, despite what all those economics book preach to us!!
