Only fish-eye lens has about as same angle of view which is 180 degrees as human sight. But, as those who use fish-eye lens know, that lens jams all the view in the viewfinder into the circle frame, which makes a picture unnaturally (at the same time, which is an attractive point of that lens, though).

Like I said in the previous sentence "one of the original...", several kinds of panoramic camera were invented. So, let's take a brief look at these structures for the next.

1. The lens unit moves and the film is fixed when the shutter is released.
- Swing-Lens panoramic camera & Revolving Lens panoramic camera

2. The camera body itself rotates or the film is transported in order when the shutter is released.
- The type of exposing the light from right to left on the flat surface of the film.
- The type that the roll film advances in order and is exposed while the shutter is released.

There is also a minor type like the one whose lens is developed only for panoramic photography.
In addition, the mechanism that a panoramic photography is taken through fixed super-wide lens on a flat surface or bent film is often found on modern cameras, especiallly on compact cameras with panoramic picture mode.
