The Nikon Fisheye Camera was discontinued in September 1961, and Nikon subsequently introduced the first regular production fisheye lens for miniature cameras in 1962, the Fish-eye-Nikkor 8 mm f /8, which required the reflex mirror on its Nikon F and Nikkormat cameras to be locked up prior to mounting the lens.

Oops wrong sauce

 

It wasn’t until 1935 that german inventors filed a patent for an optical lens that more-or-less recreated this phenomenon using glass instead of water: a patent for a 180° circular fisheye lens that they shared with a Japanese company you may have heard of: Nikon. Fast forward to 1957, and Nikon’s first $27,000 180° fisheye lens—an icon among photo history nerds—was born.

The grainy, barely legible image above was taken on October 24, 1946, from an altitude of 65 miles above the surface of New Mexico.

 

still no curve visible?

supposedly at 15 miles

imagine the curve at 65

 

Students from the University of Leicester filmed breathtaking views of cloud tops and the curvature of the earth using a high altitude weather balloon.

 

The ballon captured beautiful near-space images of Earth from 15 miles above the planet surface and in temperatures of around -56C.

 

The unmanned balloon, named by the students as Aether One, reached altitudes nearly twice as high as a 747 airliner can be operated at.
