Nikkor, Nikons brand of lenses, has been around for almost a century, and every now and then an old gem appears on eBay. This one will run you $62,000.
Introduced in 1972, the Nikkor 6mm f/2.8 was rare to begin with, with only a few lenses originally built, and features an astounding 220-degree field of view, 40 degrees more than any standard fisheye lens today, which means it can see behind itself.
Every time i find some good reasons to think Canon was the better lens maker of the Big Four (Canon, Nikon, Minolta, Pentax), i remember the 6mm f2.8 lens... and stand in awe of Nikon optical engineers.
"which means it can see behind itself. "
Hyperbolic rubbish. It would need 360 degrees to do that. Pop Mech is living up to it's name.
But, that really was an astounding lens, a true tour de force.

my leitz fisheye can see 180 degrees diagonally, which means it can see 90 degrees to the side, or directly off to my left or right. So one with a 220 angle of view is seeing 110 degrees left or right from straight ahead. That means it is seeing stuff that is in back of whoever is holding the lens.
So maybe not "behind" the lens, per se, but it is behind the flat plane defined by measuring 90 degrees from straight ahead of where it the lens looking. This lens sees a round image too, I believe, so it is seeing behind that plane in a big circle.
close enough, sez I. Your results may differ.
this is fun -- the owner's manual refers to using a lens doubler on one of those things. Double it to a whopping 12mm? Wow!
