The Canon 8-15 F4L is pretty unique. If I'm not mistaken, I don't think there has ever been another fisheye zoom lens on the market.

1200mm f5.6 is a wide angle compared to the Canon 5200mm F14 Prime Lens. Yea, it's a mirror lens, but it's still 5200mm. 5200mm Canon Lens World's MOST powerful Super telephoto EF FD (updated upload)
Id love this for shooting weddings from home.
