Ok, this is pretty impressive and also extremely cool. Industrial and interaction designers, Rob Englert and Meyer Giordano have created a very unique lens for, in this case, Nikon F mount that lets you get a full 360° field of view and 180° vertically in a single shot with no stitching required.
The pair founded Sphere Optics (aka “(sphere)”). Their first lens is called the (sphere) Pro1, which they describe as “the world’s first and only single-lens 360° full-spherical capture solution”. It has a focal length of 1mm with a fixed f/8 aperture and it sure does look pretty crazy on the camera. Its design, though, is a thing of beauty and has a level of obviousness that it’s amazing nobody ever did it before.
