Fisheye lenses are a type of ultra wide angle lens that produces visual distortion where vertical and horizontal lines become more circular in appearance. Creating a 180-degree view, fisheye lenses can produce curved panoramic or hemispherical images. Invented in 1906 by Robert W. Wood, the fisheye camera lens mimics how a fish would see the world beneath the water. Today, it's easy to find fisheye lenses for popular camera brands like Canon, Sony & Nikon.
Able to be used with DSLR or mirrorless cameras, fisheye lenses are available in two types: full frame and circular fisheye lens. Both provide the same visual distortion, except full-frame fisheye lenses fill the entire frame from edge to edge, whereas the circular fisheye lens produces an image within a circle with a black background surrounding it.
What Is a Fisheye Lens Used for?
The fisheye lens is commonly used for underwater photography, as well as landscape, architecture, and sports photography. A creative lens, fisheye lenses can bring a fresh new perspective on old subjects and the world around you. Step out of your comfort zone and see the world in a new way with the fisheye camera lens.
Is a Fisheye Lens Concave or Convex?
The fisheye lens is convex. Unlike the typical straight-line images or rectilinear images produced by an average lens, the fisheye lens creates a convex image or non-rectilinear image. The fisheye lens uses special mapping, which gives it its unique distortion and convex appearance.
